Answer:
B. The interactions of the different R group with other R groups and with their environment determine the tertiary structure of the protein
Explanation:
Protein is one of the four major biomolecules in living systems. Structurally, proteins consists of four levels namely: primary, secondary, tertiary and quartenary. The primary structure constitutes the AMINO ACIDS monomer that makes up the protein.
According to this question, the tertiary structure of the protein is formed as a result of the interaction of different R groups with one another and their environment. The R group is one of the four parts of the amino acid structure which is different for all amino acids.
These R groups interact in such a way that forms different bonds such as hydrogen bonds, disulphide bridges, hydrophobic & hydrophilic interactions etc, which leads to the tertiary structure of proteins (three-dimensional shape).
