The sequence for the Beta Actin gene (ACTB) is given below. Which pair of primers (designed to amplify the entire sequence below) could be used to successfully produce the beta actin PCR product. Circle your answer (note all sequences are written 5' to 3').
a) Forward = ggctcacagcgcgcccggctat
Reverse = taaaagtgcacaccttaaaaatga
b) Forward = tatcggcccgcgcgacactcgg
Reverse = tcatttttaaggtgtgcactttta
c) Forward = ggctcacagcgcgcccggctat
d) Forward = atagccgggcgcgctgtagcc
