If the coding strand of a transcription unit reads 5'-ATGCATGCATGC-3', the mRNA transcribed will be:
A{'text': "5'-AUGCAUGCAUGC-3'", 'label': 'A'}
B{'text': "5'-UACGUACGUACG-3'", 'label': 'B'}
C{'text': "3'-AUGCAUGCAUGC-5'", 'label': 'C'}
D{'text': "5'-GCAUGCAUGCAU-3'", 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': "5'-AUGCAUGCAUGC-3'", 'label': 'A'}
The mRNA has the same 5' to 3' sequence as the coding strand, with U replacing T. So 5'-ATGCATGCATGC-3' coding gives 5'-AUGCAUGCAUGC-3' mRNA.
