-After many cycles, millions of copies of the DNA can be produced. -This is useful in DNA fingerprinting, as researchers can do many tests on the same DNA sample. The first step to making a genetic fingerprint requires getting a sample of DNA.This sample can come from blood, semen, hair or saliva, and may be an extremely small sample.CR can be used in DNA fingerprinting as a way to make numerous copies of isolated DNA. The process can selectively amplify a single copy of a desired sequence. First Cycle: -Dna molecules are melted by raising the temperature to 95 degrees Celcius.
Genetics has always been concerned with the problem of how the hereditary information in DNA controls what an organism looks like and how it works. Classically this involved the use of genetic variants (mutants) to upset the biological function of the cells or organisms and, from the effect of these mutations, to make deductions about the way cells and organisms worked.
