Question

Determine how many of the listed terms (four are possible) can be correctly used to fill in the missing blank. Of the four possible structural elements (primary, secondary, tertiary, quaternary) changing the amino acid sequence of a MONOMERIC protein might be expected to alter __________ of them.

a.) 1

b.) 2

c.) 3

d.) All 4

Answer 1

d) All 4

The structure of all four – primary, secondary and tertiary would be altered with the change in the amino acid sequence of monomeric proteins as the change in amino acid sequence alters the primary structure. The primary structure is the polypeptide chain which consists of the amino acid and as the amino acid is changed, it alters the polypeptide chain that alter the primary structure and hence is followed by altering the secondary and tertiary structure.
