DNA extraction
AIM: To extract, and observe, Deoxyribonucleic Acid (DNA) from cells BACKGROUND INFORMATION: DNA is the genetic material that directs a cell’s activities and structure. ... DNA occurs in a doulble strand structure which is called a double helix. The information that controls the structure and function of the cell is stored in the DNA. And thus the DNA is used to develop particular structures and functions within a cell. Most of a cells DNA is generally found in the nucleus of a cell in the form of chromosomes. ... the mixture was centrifuged for 2 mins until a will-packed pellet was formed, this pellet was mainly starch and DNA was in the supernatant liquid 11. ... It was poured carefully so that the ethanol floated to the top of the DNA solution and did not mix with it. ... the layer where the ethanol touched the DNA solution was gently stirred with a glass rod and observations were made of the DNA.
