You are practicing designing primers that you can use in PCR reactions. You want your primers to allow you to amplify the sequence found below.

 

 

(a) 5’-ACTTCGATATGTCTAAAATAC-3’ and 5’- CGGTAGCGTCTCTGGTTAGCT -3’

(b) 5’-TGAAGCTATACAGATTTTATG-3’ and 5’-GCCATCGCAGAGACCAATCGA-3’

(c) 5’-GTATTTTAGACATATCGAAGT -3’ and 5’-AGCTAACCAGAGACGCTACCG-3’

You are asked to design a 15-nucleotide-long primer that could potentially hybridize to a portion of a specific mRNA that encodes the protein sequence N-Met-Ala-Tyr-Trp-Pro-C. How many different primers would you have to design in order to ensure that one of them will in fact hybridize along its full length to the mRNA?
