The Extraction and Purification of DNA.

Deoxyribonucleic Acid, commonly referred to as DNA, is the molecule found in everything termed as living. The DNA molecule contains a genetic code that is for every organism, therefore, acting as a blueprint for continuous plans for any substance that the organisms do produce in the course of their lives. Interestingly, as popular as the term DNA appears to be, very few people have had a chance to see the molecule simply because the molecule happens to be very small for one to easily see. However, one can simply do extraction on the molecules easily at home or in the school using available household materials like plants and especially peas.

Some of the essential materials you will need for the extraction process include alcohol, meat tenderizer, split peas, dishwashing detergent probably in liquid form, a blender, a beaker or clear glass container, a stirring rod or a spoon. In the first procedure, blend at least a half cup of split peas in a cupful of water. With the soupy mixture you have got from blending, use a homogenous solution to separate the mixture. One may also consider keeping the extra solution just in case. After obtaining the solution, consider pouring some of it into a container up to a level of at least two inches, the solution used here should be adequate.

In the third step, you need to add at least a tablespoonful of the liquid dishwashing detergent on top of the solution. Then consider stirring the mixture slowly for about five minutes. The next step you should add a pinch of the meat tenderizer to the solution then stir for another five minutes. After stirring the mixture, drizzle some alcohol above the container. Consider adding the alcohol until you obtain a layer of three inches on the split peas solution. Peas are mostly used for this extraction because they are so rich in the molecule. Again the detergent is used to break down the membrane cell for it to release its contents and the meat tenderizer to dissolve the membrane nuclear for it to release the DNA inside. The alcohol is used to bring out the DNA strands.

The purification procedure can utilize various processing kits. This is because, different samples work with different kind of tissues, forensic samples, plant parts and also cellular structure. Continuously, there are new inventions being made on machines and cutting edge products through different forms of amplification and facilitations for use in new projects and experiments. Among these ways are the use of magnetic beads and the way happens to be very effective. Another way involves the use of plasmid purification kits which is able to give low endotoxin levels for use in the subject transfection.
