Which structural level of protein is least affected by a disruption in hydrogen bonding?

Question

A. primary level

B. Secondary Level

C. Tertiary level

D. Quaternary level

E. All structural levels are equally affected.

Answer 1

The answer is A. The other levels (BCD) are affected by hydrogen bonding. Look at the second level where you have Beta-sheets and alpha-helixes, which rely on hydrogen bonding to produce these shapes.

good luck.

Answer 2

I shall guess 'A' the primary level is least affected by disrupted hydrogen bonding.  Presumably the hydrogen bonds play a role in the folding and coiling of the protein structure, affecting the more complex structures to a greater extent.

Answer 3

Exactly A.
