Solution

The correct option is C UAUGC
During transcription, if the nucleotide sequence of the DNA strand that is being coded is ATACG, then the nucleotide sequence in the mRNA would be UAUGC because in RNA, the bases are adenine (A), cytosine (C), guanine (G), or uracil (U). Adenine and guanine are purines, cytosine and uracil are pyrimidines. Purines and pyramidines form complimentary base pairs and this process is also called as complimentary base pairing.
