Solution

Answer A. Forward Primer GAA TTC ATG CGT AGA TCG

Answer B reverse primer    GAA TCT ATC CTA CAT CTA

Answer C. Given sequence is the sequence of the mRNA because it has Uracil instead of thymine so when we design the primer we have to replace U to T.

Forward primer- ATC GAT GAC GAT GGA CGA

Answer D. Given sequence is the sequence of the mRNA because it has Uracil instead of thymine so when we design the primer we have to replace U to T.

None of the options are right

Answer will be - AT CGC TCT ATC TCG TCT TTT TCG
