European kestrels feed on Microtus voles, with the "kill" rate, defined as the number of prey taken during the breeding season, as linearly proportional to the density of Microtus. This type of functional response is referred to as

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."

this protocol provides a detailed procedure for agarose-based ip to purify and enrich the protein of interest.
