A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus, and that the purple allele (C) is dominant to the pink allele (c). A random sample of 1000 tulips from a large cultivated field yields 847 purple flowers, and 153 pink flowers.
a. Determine the frequency of the purple and pink alleles in this field population.
b. Estimate the proportion of all purple flowering plants that are heterozygotes and homozygotes.
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476
Answer:
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476
Explanation:
Given -
Purple flowers - 847
Pink flowers - 153
The frequency of recessive genotype i.e
[tex]q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\[/tex]
Frequency of recessive allele i.e q is equal to
[tex]q = \sqrt{0.153} \\q = 0.391[/tex]
As per hardy Weinberg's first equilibrium equation -
[tex]p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609[/tex]
Frequency of purple homozygous species
[tex]= p^2\\= 0.609^2\\= 0.371[/tex]
Number of purple homozygous species [tex]= 0.371 * 1000= 371[/tex]
Number of pink homozygous species [tex]= 0.153 * 1000= 153[/tex]
Heterozygous species is equal to
[tex](1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476[/tex]
Answer:
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, purple heterozygotes = 476
Explanation:
According to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where, p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of dominant homozygous genotype
2pq = frequency of heterozygous genotype
q² = frequency of homozygous recessive genotype
a. Assuming the population is in Hardy-Weinberg equilibrium,
frequency of pink flowers (cc) = q² = 153/1000 = 0.153
frequency of pink allele c = q = √0.153 = 0.391
p + q = 1 where p = frequency of dominant allele
So, frequency of purple allele C = p = 1-0.391 = 0.609
b. Purple homozygotes = CC = p² * total population =
(0.609)² * 1000 = 370.88 = 371
Purple heterozygotes = Cc = 2pq * total population =
2 * 0.609 * 0.391 * 1000 = 476.23 = 476

When people receive organ transplants, they often need to take medications that decrease immune responses because:________
(1) transplanted organs contain antigens that can trigger white blood cell activity
(2) hormones present in replacement organs prevent the synthesis of antibiotics
(3) transplanted organs produce their own antibiotics
(4) antigens present in these organs attack antibodies already present in the blood
Answer:
Option 1
Explanation:
The organ transplanted is a foreign element for the body and the medication prescribed after transplantation surgery prevents this organ from the attack of immune system of the body.
Since the immune system is in habit of attacking all foreign agents, it poses highest risk in transplantation surgery and hence effective medication can prevent the organ form being rejected.
In general, immuno-suppressant or anti-rejection drugs are given to the patient. Along with anti-rejection drug some additional drugs are given to eradicate the side effects of anti-rejection drugs.

Imagine that you've discovered a regulatory sequence thousands of base pairs away from the promoter and that when this sequence is lost due to mutation, levels of gene expression decrease sharply. This sequence is most likely ______.
A. A silencerB. An enhancerC. A promoter-proximal elementD. A promoter
Answer:
An Enhancer
Explanation:
Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.
According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.

Which of the following statements describes integral membrane proteins?
I. They protect the contents of the cell from chaotropic agents such as urea.
II. They are easily dissociated from the membrane by changes in pH or high salt concentration.
III. They are held tightly in place by hydrophobic effects between the membrane and hydrophobic amino acids.
Integral membrane proteins are essentially permanently attached to the cell membranes due to hydrophobic effects. They are not easily removed and their functions can greatly vary.
Explanation:The term integral membrane proteins refers to proteins that are permanently embedded in the biological membrane. They are tightly held in place by hydrophobic effects between the lipophilic or hydrophobic amino acids of the protein and the fatty acid chains of the membrane lipids, making statement III correct. They are not easily dissociated from the membrane by changes in pH or high salt concentration, contradicting statement II.

Integral membrane proteins are firmly embedded in the biological membrane due to hydrophobic interactions, and are not easily dissociated by changes in pH or high salt concentration. They are not specifically responsible for protection against chaotropic agents like urea.
Explanation:Integral membrane proteins are a type of protein that is permanently attached to the biological membrane. Among the statements provided, the one which accurately describes integral membrane proteins is III: 'They are held tightly in place by hydrophobic effects between the membrane and hydrophobic amino acids.' This is due to their structure, which typically includes a hydrophilic 'head' and a hydrophobic 'tail', allowing them to interact with both the interior of the lipid bilayer and the aqueous environment outside the cell.
However, the statements I and II are not entirely accurate. While integral membrane proteins do play a role in the cell's defenses (statement I), including against certain types of toxins, they aren't specifically designed to protect against chaotropic agents like urea. For statement II, it is misleading, because integral membrane proteins are not easily dissociated from the membrane simply by changes in pH or high salt concentration – these proteins are firmly embedded in the membrane due to the hydrophobic interactions between the protein and the lipid bilayer.

When gene duplication occurs to its ultimate extent by doubling all genes in a genome
The gene duplication occurs to its ultimate extent by doubling all genes in a genome during mitosis.
Explanation:
Mitosis is a process by which an Eukaryotic organism divides its cells into two cell keeping all the genetic setup and the genetic configurations same. During mitosis, at first, during the G0 phase of mitosis, the cell prepares itself for mitosis, where it duplicates its DNA and some of the other proteins required during cell division.
During the mitosis these DNAs concentrate as different chromosomes and are separated and pulled apart into two different poles by spindle fibers and two new cells are eventually formed. Thus, during mitosis, cells produce ultimate gene duplication.
A sperm cell's acrosome ______.
A) contains the sperm's mitochondria
B) fuses with the plasma membrane of the egg cell
C) contains enzymes that are released when the sperm encounters an egg and dissolves a hole in the jellylike matrix that surrounds the egg
D) contains the sperm's nucleus and is the part of the sperm that enters the egg during fertilization
Answer:
C
Explanation:
Sperm cells do a great and tasking job in their quest for egg fertilization. First, they have to find an egg to fertilize by swimming a long distance, as not all released sperm finds an egg. The few that finds an egg still have to cross the egg's protective coat and fuse their own membrane with the plasma membrane of the the egg. This process of crossing the egg's barrier is referred to as ACROSOME reaction.
The acrosome is a lysosome-like vesicle located in between the sperm's plasma membrane and nuclear membrane (nucleus) derived from the golgi complex of the spermatid. It is closer to the plasma membrane at the tip of the sperm's head. The vesicle contains soluble proteolytic enzymes such as acrosin and inner membrane proteins such as bindin.
The acrosome reaction is the exocytosis of the acrosome, or the fusion of the acrosomal membrane with the sperm's plasma membrane. The process releases the acrosomal contents (lytic enzymes) to the outside of the sperm.
When the acrosome's proteolytic enzymes are released, they begin to degrade the egg's protein-rich protective coat. The egg's plasma membrane is surrounded by a thick ZONA PELLUCIDA layer made of extracellular matrix and a jelly-like cumulus layer surrounding it. This degradation creates a path for the sperm to swim through on its way to the egg's plasma membrane. This enables the plasma membranes of the egg and sperm to fuse placing both haploid nuclei (one from the sperm, the other from the egg) into the same cell, where they form the diploid genome of the new organism.
In pea plants, the allele for purple flower color is dominant to the allele for white flower color. If you were to perform a test cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous? And what would you expect if the plant is heterozygous?
A. If the purple-flowered plant is homozygous, then the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:1 ratio.
B. If the purple-flowered plant is homozygous, than the progeny would all have white flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:1 ratio.
C. If the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1:3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:1 ratio.
D. If the purple-flowered plant is homozygous, than the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 3:1 ratio.
E. If the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1:3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:3 ratio.
The phenotypic ratio of purple-flowered to white-flowered progeny would be different depending on the genotype of the purple-flowered plant: all purple flowers if homozygous and a 1:1 ratio if heterozygous.
Explanation:In a test cross to determine the genotype of a purple-flowered plant, if the plant is homozygous for the purple flower color allele, all the progeny would have purple flowers. This is because the purple flower color allele is dominant to the white flower color allele. On the other hand, if the plant is heterozygous, the progeny would show a 1:1 phenotypic ratio of purple to white flowers.

If a double-stranded DNA molecule is like a twisted rope ladder with handrails and steps, what would the steps in the ladder represent?A. phosphate groupsB. nitrogenous basesC. DNA polymeraseD. sugar (deoxyribose) molecules
Final answer:
In the twisted ladder model of DNA, the steps or rungs represent the nitrogenous bases—adenine, thymine, guanine, and cytosine—which pair together to form the structure of the DNA ladder.
Explanation:
If we liken a double-stranded DNA molecule to a twisted rope ladder, the steps in the ladder represent the nitrogenous bases. More specifically, these bases are adenine (A), thymine (T), cytosine (C), and guanine (G). In the DNA structure, adenine always pairs with thymine and guanine with cytosine. These pairings create the rungs of the ladder.
It is essential to note the ladder's rails are the sugar-phosphate backbone, which consists of alternating sugar (deoxyribose) and phosphate groups. On each side of the ladder, a strand of this backbone runs in opposite directions (antiparallel) which is crucial for the function and replication of DNA.
The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?
Answer:
UAC
Explanation:
This example portrays that translation, which is the second process of protein synthesis, is about to occur. Translation cannot occur without a special type of RNA called tRNA or transfer RNA.
A tRNA contains a set of three nucleotides called ANTICODON. The tRNA matches an mRNA codon with the amino acid it encodes. The tRNA initially binds to the mRNA and reads the mRNA codon using its anticodon (which is complementary to the mRNA's codon). The actual reading is done by matching the base pairs through hydrogen bonding following the base pairing rule i.e. A-U, G-C. After reading the mRNA codon using its anticodon, it then carries the specific amino acid encoded by that codon it binds to, in order to add to the growing polypeptide chain.
For example, a codon AUG (start codon that signals beginning of translation) will be read by tRNA anticodon, UAC. Since the codon AUG codes for amino acid, Methionine. The tRNA then carries Methionine via its amino acid attachment site and adds to the polypeptide chain (future protein).

The scientist's prediction provides the strongest support for which of these conclusions? A. The gibbon population will decrease by 5 percent every year until reaching a certain minimum size, which it will maintain. B. The gibbon population will decrease by 10 percent every year until reaching a certain minimum size, which it will maintain. C. Gibbons will maintain their current population size as they adapt to new environments. D. Gibbons will eventually become extinct in the wild.
The scientist's prediction that Southeast Asia's carrying capacity for gibbons will decrease by 10 percent due to deforestation supports the conclusion that the gibbon population will also decrease by 10 percent yearly until stabilized at a minimum size (which corresponds to option B).
A scientist predicts that due to ongoing deforestation in Southeast Asia, the carrying capacity for gibbons will decrease by 10 percent every year. This prediction strongest supports the conclusion that the gibbon population will decrease by 10 percent every year until it reaches a minimum size, which it will then maintain (which corresponds to option B). This conclusion assumes that the gibbons' population size is directly correlated with the carrying capacity of the environment, which in this case is decreasing due to deforestation. As the carrying capacity shrinks, the number of gibbons that the region can sustain also goes down, potentially leading to a continuous decline in population until a new equilibrium with the reduced carrying capacity is found.
