Can potassium chloride andsodium chloride be separated by sublimation?

No, because neither of them sublimate at 760 torr (1 atm). They melt. You could separate them by melting point, as NaCl has a melting point of 801ºC, but KCl has a melting point of 770ºC.

How has the lab technique PCR helped scientists study evolutionary relationships?

PCR helps, specifically, with finding homology between sequences of dna quickly and spefically where scientists want to look in the genomes. PCR, by using 'primers,' pinpoint exactly where they want to make copies of DNA. By making these copies, they can be read by a machine and from there, 'multiple sequence alignment' can be performed to examine evolutionary relationships. These sequences and homology matter to scientists such as structural biologists who want to find out the specific 3D shape of homologous proteins or RNA. They can use homology in, say mice (mammal) DNA sequences to make predictions about the shape of human proteins/RNA--therefore finding ways to attack a 3D structure with a new synthetic medicine.
