Editing DNA extraction (section)

== What does it deliver? ==
DNA extraction is frequently a preliminary step in many diagnostic procedures used to identify environmental viruses and bacteria and diagnose illnesses and hereditary diseases. These methods consist of, but are not limited to:

Fluorescence In Situ Hybridization (FISH) technique was developed in the 1980s. The basic idea is to use a nucleic acid probe to hybridize nuclear DNA from either interphase cells or metaphase chromosomes attached to a microscopic slide. It is a molecular method used, among other things, to recognize and count particular bacterial groupings.<ref name=":0" />

To recognize, define, and quantify the geographical and temporal patterns in marine bacterioplankton communities, researchers employ a technique called terminal restriction fragment length polymorphism (T-RFLP).

Sequencing: Whole or partial genomes and other chromosomal components, ended for comparison with previously published sequences.<ref>{{Cite web |last=Rice |first=George |date=2006-12-08 |title=DNA Extraction |url=https://serc.carleton.edu/microbelife/research_methods/genomics/dnaext.html |access-date=2022-10-09 |website=Science Education Resource Center at Carleton College |language=en}}</ref>
