Who Found Out That Dna Is In Genetic Material By Using A Blender

DNA is the genetic material of all organisms. Extraction and purification of DNA is the first step in many molecular biology experiments. Whether a scientist is interested in studying an organism’s entire genome or cloning a gene from that organism, the extraction of DNA involves the same three steps:

To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene.
