Think about the function of the primers in a PCR that is designed to amplify a specific sequence, and about the temperatures of the PCR cycle. After considering these two points, give two reasons why 4-nucleotide long primers are not appropriate for PCR and explain.

An individual is heterozygous for an allele. Allele A has a SNP that results in disruption of an Not1 restriction enzyme site. Allele B has a functional Not1 restriction enzyme site. PCR is performed on the region of the gene containing the SNP to produce a 255bp PCR product. Restriction digestion was subsequently performed using EcoR1 restriction enzyme and the fragments were electrophoresed on an agarose gel. (EcoR1 cuts allele B at a site 115bp from the end of the sequence.) What are the sizes of the subsequent DNA fragments? 1) 115bp + 140bp 2) 205bp + 255bp 3) 140bp 4) 205bp + 255bp + 115bp 5) 140bp + 205bp + 255bp 6) 255bp + 115bp + 140bp 7) 115bp 8) 255bp 9) 115bp + 255bp 10) 255bp + 115bp + 140bp + 205bp 11) 140bp + 205bp 12) 205bp 13) 205bp + 115bp 14) 140bp + 255bp
