The coding strand sequence is 5' TAGCTAGCTAGCTAC 3', and the corresponding mRNA sequence is 5' UCAGUCAGUCAGUAC 3'. In the mRNA, uracil substitutes for thymine found in the coding strand.

1. (a)
2. (b)
3. (c)
4. (d)

Correct answer: (d)

Solution

mRNA has the same sequence as the coding DNA strand except that uracil (U) replaces thymine (T). Since the given mRNA is 5' UCAGUCAGUCAGUAC 3', the correct option is the one showing that exact pattern relative to the coding strand, which is (d).
