Introduction to DNA Extractions
Introduction to DNA Extractions
Description:
There are two to three basic steps in DNA extraction. The cell must be lysed (broken open) to release the nucleus. The nucleus (if present) must also be opened to release the DNA. At this point the DNA must be protected from enzymes that will degrade it, causing shearing. Once the DNA is released, it must then be precipitated in alcohol. These labs extract DNA from onions, wheat germ, lima beans, yeast and thymus.
