Which one of the following is the sequence on corresponding coding strand, if the sequence on mRNA formed is as follows 5' AUCGAUCGAUCGAUCGAUCGAUCG AUCG 3'?

A

5' UAGCUAGCUAGCUAGCUAGCUAGC UAGC 3'

B

3' UAGCUAGCUAGCUAGCUAGCUAGC UAGC 5'

C

5' ATCGATCGATCGATCGATCGATCG ATCG 3'

D

3' ATCGATCGATCGATCGATCGATCG ATCG 5'

Step-by-Step Solution

The coding strand of DNA has the same sequence as the mRNA, except that Thymine (T) replaces Uracil (U). Given mRNA: 5' AUCGAUCGAUCGAUCGAUCGAUCG AUCG 3'. The coding strand will be: 5' ATCGATCGATCGATCGATCGATCG ATCG 3'.
