Questions and Answers

What are proteins composed of?

Proteins are composed of one or more long chains of amino acid residues.

What are some functions of proteins within organisms?

Proteins perform functions such as catalyzing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules.

How do proteins differ from one another?

Proteins differ primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and usually results in protein folding into a specific 3D structure that determines its activity.
