The answer is the second one (C-terminal): the original text in the question...

Explanation:

  1. In the polypeptide Ser-Cys-Ala-Gly, Gly is the C-terminal amino acid.

    • Polypeptides are chains of amino acids linked by peptide bonds. The sequence is read from the N-terminal (the end with a free amino group) to the C-terminal (the end with a free carboxyl group). In the given sequence, Ser is at the N-terminal, and Gly is at the C-terminal.

  2. In the nucleotide sequence ATCG, the nucleotide G is the 3' nucleotide.

    • Nucleotide sequences are read from the 5' end to the 3' end. In the given sequence, A is at the 5' end, and G is at the 3' end.

Summary:

  • Gly is the C-terminal amino acid in the polypeptide Ser-Cys-Ala-Gly.
  • G is the 3' nucleotide in the nucleotide sequence ATCG.
