G"In the β-pleated sheet secondary structure of a protein, two or more amino acid sequences in separate parts of the protein are held together" A) in a coil, by hydrogen bonding. B) in random order, due to hydrophobic interactions. C) in a triple helix. D) in a double helix. E) in a zig-zag conformation, by hydrogen bonding.

Option A .

In a coil by Hydrogen bonding.

Explanation:

B - pleated sheet secondary structure of protein is a regular element of secondary protein structure which consist of beta strands. In B pleated sheet, two or more segments or strands of polypeptide chain lie at the side of each other to form sheet which is held by Hydrogen bonding. The G in B pleated sheet form a coil and are held by Hydrogen bonding. This bond is formed by carbonyl and amino acid group.
