Q. If the sequence of nitrogen bases of the coding strand of DNA in a transcription unit is: 5’ – A T G A A T G – 3’, the sequence of bases in its RNA transcript would be
A) 5’ – A U G A A U G – 3’
B) 5’ – U A C U U A C – 3’
C) 5’ – C A U U C A U – 3’
D) 5’ – G U A A G U A – 3’
Explanation
The base sequence of coding strand and mRNA transcript is same except uracil (U) is found in RNA instead of thymine (T).
