The MRNA Sequence That is Complementary to the Sequence ATC

Question

The mRNA sequence that is complementary to the sequence ATC on DNA is
A) ATC.
B) TAG.
C) UAG.
D) AUG.
E) AUC.

Accepted Answer

RNA is synthesized using the complementary base pairing rules, with the exception that thymine (T) is replaced with uracil (U) in RNA. Therefore, the complementary mRNA sequence to the DNA sequence ATC would be UAG.
