In the primary structure of a protein, the sequence of amino acids is often imagined as a line. According to this convention, the right end of the line represents the:

Step-by-step solution

According to NCERT, the primary structure of a protein provides positional information in a protein, which is the sequence of amino acids. A protein is imagined as a line, where the left end represents the first amino acid and the right end represents the last amino acid. The first amino acid is also called the N-terminal amino acid, and the last amino acid is called the C-terminal amino acid. Therefore, the right end of the line represents the last amino acid, which is the C-terminal amino acid. Answer: Last amino
