Question

Which sets of mRNA codons could genetically code for a protein with the following amino acid composition:

Pro - Asp - Gly - Lys

A)CCC - AAU - CAA - GAA
B)CCC - GAU - GGG - CAA
C)UUC - GAU - AAG - AAU
D)CCA - GAC - GGC - AAA

Answer 1

I think is D)... sorry if you get it wrong but is the one that make more sense

Answer 2

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.'
