Question

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'

Answer 1

A. 5' - A U G A A U G - 3' is the correct option.

Answer 2

The RNA transcript would be the same as coding with one change - U in place of T.

So the answer is a. 5' - A U G A A U G - 3'
