Answer:
The correct answer is A.
Explanation:
the reason for this is that the corresponding codon in the RNA is complementary to the TEMPLATE STRAND of DNA .i.e mRNA always proceed in a 5'to 3'direction.
since the DNA template strand is 5'GAT3' ,so the corresponding coding strand of DNA which is complementary to the template strand would be 5'ATC3'. and thus the corresponding codon in the RNA transcript would be 5'AUC3'. because the sequence of the mRNA is complementary to the tempelate strand and identical to the coding strand but with the base URACIL subsituted for THYMINE.
HENCE THE CORRECT ANS WOULD BE "A".
