There's an easy way to make the abstract idea of tiny DNA tangible ... so here are three experiments you can try at home to make genetics and DNA a little more tangible. Strawberry DNA extraction. DNA extraction methods follow some common steps: lysis, purification, and DNA recovery. These steps aim to effectively lyse cells, denature protein complexes, remove biological and chemical contaminants and, finally, recover the DNA. The simplest methods rely only on the lysis step.
DNA is also negatively charged and attracts the positively charged sodium ions. This neutralises the charge on the DNA, which allows the strands of DNA to stick together and form the clumps we will see later inthe experiment. 4 - Add the extraction buffer to the mashed up kiwi and MASH! The more you mash, the more DNA you will get out at the end. DNA extraction is used as the initial step in manufacturing a number of pharmaceuticals. Pharmaceuticals made via recombinant genetics include the Hepatitis B vaccine and human growth hormone (hGh). In addition to a number of other hormones created using DNA extraction, one of the most widely used is insulin.
