Frieda is developing a computer model of mutations in human DNA. She plans for the model to incorporate one point mutation for every 10 million base pairs of DNA, which is a rate that is supported by her research. However, her advisor argues that mutations could occur 100 times more frequently under certain circumstances.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

c. heat from the poles back down towards the equator.
