The pcr (polymerase chain reaction) protocol that is currently used in laboratories was facilitated by the discovery of a bacterium called thermus aquaticus in a hot spring inside yellowstone national park, in wyoming. this organism contains a heat-stable form of dna polymerase known as taq polymerase, which continues to function even after it has been heated to 95°c. a. why would such a heat-stable polymerase be beneficial in pcr? b. what would happen if it weren’t heat stable? c. how might you choose a region of dna for a pcr primer so as to increase the temperature necessary for primer annealing (to minimize nonspecific pcr products)? d. a pcr reaction begins with 5 double stranded segment of dna. estimate the number of double-stranded copies of dna that are present after the completion of 15 amplification cycles?

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
