a protein is a large polypeptide. polypeptides are polymers of amino acids joined together through a special type of bond: the peptide bond. understanding the chemistry and properties of the peptide bond is fundamental to understanding protein structure (and function). first, identify the n- and c-termini of the peptide. then, identify those bonds that comprise the peptide bond for each labeled bond. finally, determine the number of amino acids in the peptide depicted. Drag the appropriate labels to their respective targets. Labels can be used once, more than once, or not at all. Targets may be empty.



Answer :

Chains of amino acids in messenger RNA / mRNA terminated with N-terminal and C-terminal. The free carboxyl group is called C-terminal, while the free amino group is called N-terminal.

Carboxyl group amino acids are not part of a  peptide bond. The carboxyl group is part of a carboxylic acid, carboxylate, or rarely a carboxylic acid derivative such as an ester. C-terminal in a protein is the protein signal needed to retain signs.

Amino acids residue in N-terminal is not part of a peptide bond and usually, although that is not in every polypeptide or protein, it’s an amine or ammonium cation. N-terminal is for targeting signals.
