    If the sequence of nitrogen bases of the coding strand of DNA in a transcription unit is5'- 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:

                  (a) 5' - A T G A A T G - 3' (coding strand)                                             5'- T A C T T A C - 3' (complementary strand)                                 5' -A U G A A U G - 3' (RNA)
