A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide...?

...sequence phe-leu-ile-val?


A: 5' AUG-CTG-CAG-TAT 3'


B: 3' AAA-GAA-TAA-CAA 5'


C: 3' AAC-GAC-GUC-AUA 5'


D: 5' TTG-CTA-CAG-TAG 3'


E: 3' AAA-AAT-ATA-ACA 5'

A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide...?
The trasncription goes from 3' to 5'in the template strand, and in DNA is not present the nucleotide U (only in RNA).


So the answers A and C are wrong because the strand of DNA presents U.


The correct answer is B.
