DNA Extraction:
DNA isolation is a routine procedure to collect DNA for subsequent molecular
or forensic analysis. There are three basic and one optional steps
in a DNA extraction:
| 1 |
Breaking the
cells open, commonly referred to as cell disruption or cell lysis,
to expose the DNA within. This is commonly achieved by grinding
or sonicating the sample. |
| 2 |
Removing membrane
lipids by adding a detergent. |
| 3 |
Removing proteins
by adding a protease (optional but almost always done). |
| 4 |
Precipitating
the DNA with an alcohol — usually ice-cold ethanol or isopropanol.
Since DNA is insoluble in these alcohols, it will aggregate together,
giving a pellet upon centrifugation. This step also removes alcohol-soluble
salt. |
DNA Analysis:
DNA profiling (also called DNA testing, DNA
typing, or
genetic fingerprinting) is a technique employed by forensic scientists
to assist in the identification of individuals on the basis of their
respective DNA profiles. DNA profiles are encrypted sets of numbers that
reflect a person's DNA makeup, which can also be used as the person's
identifier.
Deoxyribonucleic
acid (DNA) is a nucleic acid that
contains the genetic instructions used in the development and
functioning of all known living organisms and some viruses. The
main role of DNA molecules is the long-term storage of information.
DNA is often compared to a set of blueprints or a recipe, or
a code, since it contains the instructions needed to construct
other components of cells, such as proteins and RNA molecules.
The DNA segments that carry this genetic information are called
genes, but other DNA sequences have structural purposes, or are
involved in regulating the use of this genetic information. According
to Wikipedia.
