What Are The Steps For Dna Extraction?
In essence yes. Extraction of DNA in the laboratory involves using a detergent (cf washing up liquid) and salt to dissolve the cells, and alcohol to precipitate DNA. Soft fruit like strawberries and kiwi fruit can have their cells lysed with a detergent and high salt concentration releasing DNA. If you add alcohol so that it forms a boundary on top of the lysate, you can precipitate DNA by gently stiring the interface with a glass rod. DNA will then be spoolled out as a translucent fibre or mass. Other cells, like bacterial or fungal cells and indeed many other plant cells are not so easily lysed open, and other treatments (enzyme degradation of the cell wall or mechanical disruption) are needed for the DNA to be released.

T. And Sharon, P.A. 1985. The biochemistry, molecular biology and molecular genetics of nucleic acid release from plant cells. The Plant Cell 8(12):. ] Extraction of DNA from plant cells There are essentially two techniques used for extracting DNA from plant cells; one is cell lasing and the other is polymerase chain reaction (PCR). Some other options are ligation and denaturing of the DNA molecules before processing it. There are several approaches for extracting DNA from plant cells and each of them has its own limitations. Cell lasing Cell lasing is the most common and commonly used type of DNA extraction from plant cell, including fruit follicles. It is performed with a small plastic pipette connected directly to the culture medium. The cell's lasing agent, commonly polyethylene glycol (PEG), or isopropyl alcohol is dissolved in a small amount of culture medium. The pipette then connects directly to the culture medium and is shaken to precipitate.
