Solution
The correct option is A5'-UGAACUGUAGCAUGC-3' If the coding strand in a transcription unit is 5'-TGAACTGTAGCATGC-3'. Then, it is known that the sequence of mRNA is same as the coding strand of DNA. However, in RNA, thymine is replaced by uracil. Hence, the sequence of mRNA will be 5'-UGAACUGUAGCAUGC-3'.
