- BThe first amino acid is also called as N-terminal amino acid and the last amino acid is called the C-terminal
- CThis structure gives us a 3-dimensional view of a protein.
- DTertiary structure is absolutely unnecessary for the many biological activities of proteins.
Correct answer
D. Tertiary structure is absolutely unnecessary for the many biological activities of proteins.
Step-by-step solution
The first amino acid is also called N-terminal amino acid. The last amino acid is called the C-terminal amino acid. A protein thread does not exist throughout as an extended rigid rod. In addition, the long protein chain is also folded upon itself like a hollow woollen ball, giving rise to the tertiary structure (Fig. 9.3 c). This gives us a 3-dimensional view of a protein. Tertiary structure is absolutely necessary for the many biological activities of proteins.
