Answer:
absorb vitamins (especially Vitamin K)
Explanation:
The large intestine also helps in absorption of vitamins made by bacteria that normally live in the large intestine. These are friendly bacteria called commensal bacteria. There are over 700 species of bacteria that perform a variety of functions.
Bacteria in the large intestine also make some important substances, such as vitamin K, which plays an important role in blood clotting.
Answer:
480 nucleotides comprise this molecule of dna
Explanation:
According to Chargaff rule,
- Adenine is paired with thymine
- Cytosine is paired with guanine
Given in the question
Adenine residue = 120
Cytosine residue = 120
So, [A] = [T]
i.e. [A =120] = [T=120]
again, [C] = [G]
i.e. [C=120] = [G=120]
hence, total number of nucleotides present
=> [A] + [T] + [C] + [G]
=> 120 + 120 +120 +120
=> 480.
Answer:
Amino acids
Explanation:
Like a house, every molecule is formed of units (blocks) that determine their structure and function. Proteins have a diverse functions in the body and are very important in multiple biological processes. Proteins are molecules called polymers (molecules formed by monomers), the simplest units of proteins are the amino acids (building blocks). The amino acids are bind together by peptide bonds and when the chain of amino acids is less than 30 is called peptide and more than 30 is called protein. Every amino acid has a special structure and the type and number of aminoacids determinate the structure and function of the protein.
