Question

Which of the following is a characteristic of the secondary structure of a protein?

(a) Amino acid sequence

(b) Association of secondary structure

(c) Alpha helix and beta sheets

(d) Association of polypeptides

The question was asked by my school teacher while I was bunking the class.

This is a very interesting question from Biopharmaceuticals in division Biopharmaceuticals of Drug Biotechnology

Answer 1

Correct option is (c) Alpha helix and beta sheets

To explain: Secondary structure is formed by the interactions between the amino acids of a peptide chain. They are mostly alpha helix and beta sheets. Alpha-helix and b-sheet, if occur together, are found in different structural layers. Beta sheets are most stable.
