Genetic Code
If the sequence of nitrogen bases of the coding strand of DNA in a transcription unit is 5'-ATGAATG-3', the sequence of bases in its RNA transcript would be:
Select the correct option:
Solution
5'-AUGAAUG-3'
The coding strand has the same sequence as the RNA transcript (except T is replaced by U). So, 5'-ATGAATG-3' becomes 5'-AUGAAUG-3'.

Solution
Correct Answer:
5'-AUGAAUG-3'
The coding strand has the same sequence as the RNA transcript (except T is replaced by U). So, 5'-ATGAATG-3' becomes 5'-AUGAAUG-3'.
