If the sequence of the template strand in a transcription unit is 3' - TAC GAC TAT GCG ATC - 5', what will be the sequence of the newly transcribed mRNA?

Step-by-step solution

The mRNA is synthesized in the 5' 3' direction and is complementary and antiparallel to the template DNA strand. Given template strand: 3' - TAC GAC TAT GCG ATC - 5' In RNA, thymine (T) is replaced by uracil (U). The complementary base pairing rules are: T pairs with A A pairs with U C pairs with G G pairs with C Matching the bases from the 3' end of the template gives the mRNA sequence from the 5' end: TAC AUG GAC CUG TAT AUA GCG CGC ATC UAG Thus, the newly transcribed mRNA sequence is 5' - AUG CUG AUA CGC UAG - 3
