Can someone explain the D answer

48. The mature mRNA below resulted from the transcription of a gene and post-transcriptional modification. Based on this mRNA sequence, use the chart to determine the amino acid sequence of the polypeptide that is coded for by the genc S' P-P-P-AUAAAUGGUACAGUAAAUAAAAAAAAAAAAAA 3 UAL UGU UCA UUA UUG CUU CUC CCUA CUG Ccu CAU LCCA P CAA CCG?

Explanation / Answer

5’ – AUAA AUG GUA CAG UAA AUA AAAAAAAAAAAAA – 3’

                Met - Val - Gln                

Translation begins from START codon AUG which codes for Methionine.

Translation ends at STOP codon UAA, which does not code for any amino acid.

STOP codon are of three types namely UAA, UAG UGA.    

GUA codes for Valine (Val).

CAG codes for Glutamine (Gln).
