Question:
If the sequence of nitrogen bases of the coding strand in a transcription unit is 5'–ATGAATG–3', the sequence of bases in its RNA transcript would be:
If the sequence of nitrogen bases of the coding strand in a transcription unit is 5'–ATGAATG–3', the sequence of bases in its RNA transcript would be:
Show Hint
The RNA transcript is complementary to the template strand and identical to the coding strand, except uracil replaces thymine.

- 5'–AUGAAUG–3'
- 5'–UACUUAC–3'
- 5'–CAUUCAU–3'
- 5'–GUAAUGA–3'
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In transcription, the coding strand's sequence directly determines the mRNA sequence, but with uracil (U) replacing thymine (T).
Coding strand: 5'–ATGAATG–3' \item mRNA transcript: 5'–AUGAAUG–3'
