Suppose you extracted dna from a cheek cell that contains two copies of the same alu insert (one on each homologous chromosome). after 30 cycles of pcr, how many total copies of this region would be produced (assuming successful amplification)? show your work.
After n cycles of PCR = 2^n copies of the target sequence
Where n = 30 cycles as given in the problem.
Substituting this to the identified formula, let
2^30 1,073,741,824 copies of the target sequence.
Therefore, a total of 1,073,741,824 copies would be produced.

Does this experiment show that cd4 is the only membrane protein required for hiv entry? does this experiment show that cd4 is the only membrane protein required for hiv entry? no, the experiment shows that hiv does not utilize cd4 as a receptor. yes, because unbound cells are infected by hiv. yes, because the antibody to a protein other than cd4 was used. no, because the experiment does not test other membrane proteins.
Yes because actually this experiment shows that CD4 was the only membrane protein needed for HIV entry since only CD4 had an antibody added to it and the result leads to no HIV could infect the cell. If other membrane proteins present that were required for HIV entry, then it would also have gotten infected.
Answer:
yes, because the antibody to a protein other than cd4 was used.

The brain and spinal cord are covered and protected by three connective tissue layers called __________.
Final answer:
The three protective layers of connective tissue covering the brain and spinal cord are known as the meninges, consisting of the dura mater, arachnoid mater, and pia mater.
Explanation:
The brain and spinal cord are covered and protected by three connective tissue layers called meninges. These layers are, from the outermost to the innermost, the dura mater, the arachnoid mater, and the pia mater. The dura mater is a robust and durable membrane that provides a strong protective sheath over the brain and spinal cord. The arachnoid mater is a web-like layer that sits beneath the dura mater. Finally, the pia mater is a delicate membrane that closely envelopes the surface of the brain and spinal cord, following the contours of these structures closely. Between the arachnoid and pia mater lies the cerebrospinal fluid, which offers additional protection and cushioning to the central nervous system.

Where in the ocean are you likely to find animals that make their own light?
A. The mesopelagic zone
B. The continental shelf
C. The epipelagic zone
D. The Gulf Stream
Answer: Option A
Explanation: The second zone that is found in the ocean is the Mesopelagic zone. This zone lies from 651 to 3300 feet.
This zone has very less light as sunlight cannot penetrate upto this distance. There are hardly any plants founds in this zone and the animals here has the property of bioluminesence. This property produces light from the skin of the organism to distract the predators.
The common fishes and organism found here are giant squid, cuttle and some other molluscan.

Which of the following compounds may be polymers
A. Carbohydrates
B. Nucleic acids
C. Proteins
D. All of these
The option (D) is correct. All of these are polymers.
What do you mean by polymers?A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
Moreover, polymer is a large molecule or a macromolecule which essentially is a combination of many subunits. The term polymer in Greek means 'many parts'. Polymers can be found all around us. From the strand of our DNA, which is a naturally occurring biopolymer, to polypropylene which is used throughout the world as plastic.
Therefore, examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
