Question

the amino acid located at the carboxyl (c) end of the above peptide chain is the last amino acid found in this peptide. it is encoded by the codon ucc. which of the following codons could have been the next codon in the mrna for the protein? uga uaa uag uag, uaa, or uga

Explanation:

In protein - synthesis, when a peptide chain is being formed, the process can end with stop codons. The stop codons are UAA, UAG, and UGA. Since the question asks for the next possible codon in the mRNA for the protein after the last amino - acid codon, it could be a stop codon to terminate translation.

Answer:

D. UAG, UAA, or UGA
