The pepsinogen is a protein. All the proteins in the body are coded by the DNA present in the genome. The DNA's 5' -3' strand or the template strand is transcribed by the process of transcription and result in the formation of the mRNA (messenger RNA). the formation of the mRNA by the help of RNA polymerase.
Then the mRNA undergoes the process of maturation. During maturation, splicing of the introns, capping and tailing takes place. The mRNA undergoes translation and forms the amino acids, with the help of tRNA molecule. The tRNA molecules brings the amino acid according to the codon present and these amino acids form a sequence, which later assemble to form a protein.
Hence, the correct sequence would be:
1. The DNA strands unwind, and RNA polymerase binds to the template strand.
2. The synthesis of mRNA begins.
3. The mRNA undergoes intron splicing and exits the nucleus.
4. The tRNA moves through mRNA with the activated amino acids attached to it.

A. Fatty acid monomers combine to form a protein chain.
B. Amino acids dissolve monomers to form a protein chain.
C. Amino acids combine to form a protein chain.
D. Fatty acid monomers dissolve to form a protein chain.
The formation of a protein molecule is due to amino acids combining to form a protein chain. Therefore, the correct statement is option C.
What are amino acids?Amino acids combine to form a protein chain and are the building blocks of proteins, which are linked together through peptide bonds to form a polypeptide chain. The arrangement of the amino acids in the chain determines the structure and function of the protein.
Protein synthesis occurs in cells through translation, where the sequence of nucleotides in the messenger RNA determines the sequence of amino acids in the protein chain, where the mRNA is read by ribosomes, which link amino acids together using transfer RNA molecules carrying the amino acid to the ribosome.
The proteins have secondary, tertiary, and quaternary structures that are determined by the interactions between the amino acids in the chain and these interactions include hydrogen bonds, disulfide bonds, etc.
Therefore, the formation of a protein molecule links the amino acids through peptide bonds to form a polypeptide chain.

The differences between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nitrogenous bases that make up another section of the molecules. These two molecules are DNA and RNA. They differ in their sugar components (ribose in RNA, deoxyribose in DNA), and in one of the nitrogenous bases (RNA has uracil instead of thymine which is in DNA). This sets the stage for their different roles in the cell.
Explanation:Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two molecules that you are referring to. DNA and RNA are both nucleic acids, which are made up of smaller units called nucleotides. Each nucleotide is made up of three parts: a sugar, a phosphate group, and a nitrogenous base.
The type of sugar and the nitrogenous base can vary between the two. In DNA, the sugar is deoxyribose and the nitrogenous bases are adenine, cytosine, guanine, and thymine. In contrast, RNA has ribose as the sugar and its nitrogenous bases are adenine, cytosine, guanine, and uracil instead of thymine.
Furthermore, DNA usually exists as a double helix with two strands running in opposite directions and complementary to each other, while RNA is usually single-stranded. These differences in structure and composition account for their distinctive roles in the cell, with DNA storing genetic information and RNA playing a key role in protein synthesis.

Cells have blank of enzymes to act as biological
Cells contain numerous enzymes acting as biological catalysts to speed up essential biochemical reactions. These enzymes interact with specific substrates, and their activity is crucial for sustaining life, exemplified by the health issues arising from enzyme deficiencies in conditions like Sanfilippo Syndrome type B.
Explanation:Cells have a plethora of enzymes to act as biological catalysts. Enzymes are essential proteins in cells that catalyze biochemical reactions by lowering the activation energy required for the reactions to proceed. They are not consumed in the reaction, hence they can be used repeatedly. Substrates are the specific molecules that enzymes act upon, and each enzyme is specific to its substrate. For instance, the enzyme urease catalyzes the reaction involving the substrate urea. Without these biological catalysts, many necessary reactions would not occur rapidly enough to sustain life. An example of this is individuals with Sanfilippo Syndrome type B, who lack a particular enzyme, leading to cellular damage and severe health consequences.
Furthermore, enzymes can be classified according to their function: catabolic enzymes break down substrates, anabolic enzymes build complex molecules from substrates, and catalytic enzymes affect the rate of the reaction. All enzymes serve to increase the rate of chemical reactions, making them vital organic catalysts in living organisms.

how can fecal transplants cure patients infected with harmful bacteria
Fecal microbiota transplant (FMT) is a proven method with over a 90% success rate in curing patients infected with harmful bacteria like C. difficile by restoring balance to the gut microbiome using stool from healthy donors.
Fecal transplants can cure patients infected with harmful bacteria by restoring the microbiota of the gut. When antibiotics are ineffective, fecal microbiota transplant (FMT) therapy involves taking a stool sample from a healthy donor, which contains a beneficial gut microbiome, and administering it to the infected patient's colon via colonoscopy, endoscopy, sigmoidoscopy, or enema.
This introduces beneficial microbes and metabolites that help move the gut microbiome towards a balanced state, known as homeostasis. The success rate for resolving C. difficile infections using this method is reported to be over 90%. However, caution is necessary as donor samples could harbor other pathogens, so comprehensive research and optimized procedures are crucial for safety.
Fecal transplants restore healthy gut bacteria, effectively curing infections like C. diff by outcompeting harmful bacteria.
Fecal transplants, or fecal microbiota transplants (FMT), are a treatment that involves transferring stool from a healthy donor to a patient’s gastrointestinal tract. This process aims to restore the balance of healthy bacteria in the gut, particularly for patients suffering from infections caused by harmful bacteria, such as Clostridium difficile (C. diff).
When harmful bacteria overpopulate the gut, they can disrupt the normal microbiome, leading to conditions like diarrhea, abdominal pain, and more severe complications. Fecal transplants introduce a diverse community of beneficial bacteria, which helps to outcompete and eliminate the harmful bacteria.
The transplant is typically administered via colonoscopy, enema, or oral capsules. The beneficial bacteria in the donor stool repopulate the patient's gut, helping to restore its natural balance and improving gut health.
Research has shown that fecal transplants can be highly effective, with cure rates for C. diff infections exceeding ninety percent after one treatment. This success highlights the importance of the gut microbiome in overall health and disease management.
