what are the 3 steps of dna extraction?
475023
There are 3 basic steps involved in DNA extraction, that is, lysis, precipitation as well as purification. In lysis, the nucleus and the cell are broken open, thus releasing DNA.

Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.

Application. The ability to extract DNA is of primary importance to studying the genetic causes of disease and for the development of diagnostics and drugs. It is also essential for carrying out forensic science, sequencing genomes, detecting bacteria and viruses in the environment and for determining paternity.

PCR (Polymerase Chain Reaction) ... PCR involves the following three steps: Denaturation, Annealing and Extension. First, the genetic material is denatured, converting the double stranded DNA molecules to single strands. The primers are then annealed to the complementary regions of the single stranded molecules.

The DNA test is performed by collecting buccal (cheek) cells found on the inside of a person's cheek using a buccal or cheek swab. These swabs have wooden or plastic stick handles with a cotton on synthetic tip.
