Which one of the following is the sequence on corresponding coding strand, if the sequence on mRNA formed is: 5' -AUCGAUCGAUCGAUCGAUCG- 3’?

  1. A
    5’ -UAGCUAGCUAGCUAGCUA- 3’
  2. B
    3’ -UAGCUAGCUAGCUAGCUA- 5’
  3. C
    5’ -ATCGATCGATCGATCGATCG- 3’
  4. D
    3’ -ATCGATCGATCGATCGATCG- 5’

Solution & Step-by-step Explanation

The coding strand of DNA has exactly the same sequence and polarity as the mRNA, with the only difference being that DNA has Thymine (T) instead of Uracil (U).mRNA: 5' - AUCG... - 3'Coding Strand: 5' - ATCG... - 3'
