Question

How do differences in amino acid sequences lead to different protein functions?

A. Different amino acids produce different proteins based on the bonds formed between them

B. Differences in amino acids lead to the recycling of proteins, which produces other functional proteins.

C. Different amino acids cause rearrangements of amino acids to produce a functional protein.

D. Differences in the amino acids cause post-translational modification of the protein, which reassembles to produce a functional protein.

Answer 1

Differences in the amino acids cause post-translational modification of the protein, which reassembles to produce a functional protein. Proteins have to undergo post-translational modification (PTM) refers to the covalent and generally enzymatic modification of proteins following protein biosynthesis. Proteins are synthesized by ribosomes translating mRNA into polypeptide chains, which may then undergo PTM to form the mature protein product. PTMs are important components in cell signaling.
