Correct answer
D. The first amino acid in the polypeptide chain is called as C-terminal amino acid and the last amino acid is ca
Step-by-step solution
The N-terminus (also known as the amino-terminus, NH 2 -terminus, N-terminal end or amine-terminus) refers to the start of a protein or polypeptide terminated by an amino acid with a free amine group (-NH 2 ). The convention for writing peptide sequences is to put the N-terminus on the left and write the sequence from N- to C-terminus.
