If amino acids didn’t have __________, then proteins wouldn’t have a variety of __________. Select one: a. carboxyl groups / P-groups b. secondary structure / tertiary structures c. R-groups / tertiary structures d. primary structure / secondary structures e. P-groups / alpha helices

Solution

the answer is c. R groups/ tertiary structure

because the tertiary structure is formed by the different type of intramolecular interactions such as the hydrophobic , ionic , hydrogen bond between the side chains i.e. R groups which is responsible for folding up of protein into globular form thus forming tertiary structure, which is not possible in the abscence of R groups.
