PCR And Its Use
Often times, scientists only have a small amount of DNA to deal with when doing
genetic research or studies. In these situations, scientists can do one of
several things. One is to just try to work with it anyway, but this is nearly
impossible (depending on how much there is). Ther are a couple other processes
they can use, or they can use PCR. PCR is one of the more complicated, but
reliable ways to do tests on DNA when they only have a small amount to begin
with. PCR, or Polymearse Chain Reaction, is the scientific process used by
genetic scientists to clone DNA.
"A 'rapid diagnostic' technique used in the clinical microbiology lab to detect
pathogens. It relies upon amplification technology utilizingthe heat stable DNA
polymerase from a thermophilic organism." (from
http://www.genes.com/pcr/pcrinfo.html) Dr. K.Mullis recently received the Nobel
prize for inventing the technique.
This is how they go about doing this: They first get their small DNA......
