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;
1. 5' - A U G A A U G - 3'
2. 5' - U A C U U A C - 3'
3. 5' - C A U U C A U - 3'
4. 5' - G U A A G U A - 3'
the sequence of bases in its RNA transcript would be;
1. 5' - A U G A A U G - 3'
2. 5' - U A C U U A C - 3'
