(learn more) - Collecting samples involves the isolation and careful gathering of specimens of interest in a given environmental study. Methodologies employed can be as involved and diverse as the studies themselves.
(learn more) - Extraction of the genetic material from the organisms of interest is the first step in identifying them at the molecular level.
(learn more) - "Sometimes called molecular photocopying, the polymerase chain reaction (PCR) is a fast and inexpensive technique used to "amplify" - copy - small segments of DNA. Because significant amounts of a sample of DNA are necessary for molecular and genetic analyses, studies of isolated pieces of DNA are nearly impossible without PCR amplification" (from the National Human Genome Research Institute).
