Solution
The correct option is ATAG
In DNA transcription, the coding strand is the DNA strand whose base sequence corresponds to the base sequence of the RNA transcript produced (although with thymine replaced by uracil).
It is this strand which contains codons, while the non-coding strand contains anticodons.
Hence, UAG is triplet nitrogen base on m RNA, TAG will be the corresponding triplet on the coding strand.
