6. (4pts) Some people can taste the bitter taste of PTC (phenylthiocarbamide) and some don't. Usually is also related to increased tasting of spicy food, etc. Simple PCR tests were developed to confirm ability/inability to taste PTC. The SNP at position 785 is useful for determining PTC genotype since the common taster sequence in this region forms a Fnu4H1 restriction enzyme digestion (cut) site. In contrast, in the common nontaster allele, there is a T at position 785 (instead of C785)...
