Question

If the sequence of bases in the coding strand of a double-stranded DNA is 5'-GTTCGAGTC-3' the sequence of bases in its transcript will be

• A. 5'-GACUCGAAC-3'
• B. 5'-CAAGCUCAG-3'
• C. 5'-GUUCGAGUC-3'
• D. 5'-CUGAGCUUG-3'

Answer 1

The correct option is C 5'-GUUCGAGUC-3'

In the case of bases in the transcript, i.e. when mRNA is formed, the sequence will be 5'-GUUCGAGUC-3', i.e. exactly similar to the coding strand excepting at the place of thymine (T) these will be uracil (U).
