Question

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 ______.

Options

• 5' - AUGAAUG - 3'

• 5' - UACUUAC - 3'

• 5' - CAUUCAU - 3'

• 5' - GUAAGUA - 3'

Answer 1

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 5' - AUGAAUG - 3'.

Explanation:

The coding strand sequence 5' - ATGAATG - 3' corresponds to the RNA transcript sequence 5' - AUGAAUG - 3', with Thymine substituted by Uracil.
