DNA basics

Improving your understanding of DNA


To extract DNA you simply open the cell and DNA is separated


Most molecules are too large to be used for study so scientists have to trim parts off to make them small enough to analyze fully.


This is a device used to separate DNA fragments, its known as gel electrophoresis. First negatively charged molecules are placed on one end and an electricle charge is added causing them to separate.
