Ans.
Codons are three nucleotide sequences present on DNA or RNA that codes for the amino acids or provide stop signal at the time of protein synthesis. Each codon codes for a specific amino acid. The amino acid proline (pro) is coded by CCG, CCT, CCA, and CCC; aspartate (asp) is coded by GAT and GAC; glycine is coded by GGA, GGG, GGT, and GGC; and lysine is coded by AAA and AAG.
Thus, the correct answer is 'option D). CCA-GAC-GGC-AAA.'

Pepsin functions best in acidic environments and is often found in an acidic environment, particularly those with a pH of 1.5 to 2".
"Trypsins have an optimal operating pH of about 8".
It seems that the highest level of activity for the two if they were in the same environment would have to be midway between their optimum range - about pH 5
