Solution

The correct option is B Val –Arg – Thr – Tyr – Val – Arg – Thr
mRNA synthesized from this DNA would have sequence (Replace T with U on Coding strand):
5’ AUG GUA CGU ACG UAC GUA CGU ACG UAA CCG 3’
The start codon AUG which codes for methionine will be removed during processing of the polypeptide.
GUA - Valine
CGU - Arginine
ACG - Threonine
UAC - Tyrosine
UAA isa top codon so, the translation will stop at this point.
Hence, the protein will have the sequence
Val –Arg – Thr – Tyr – Val – Arg – Thr
