3. 1-Disease Diagnosis and Treatment
 One important area of DNA research is that of genetics and
medical research. Due to our discovery of DNA, our ability to
actually diagnose diseases early on has been vastly improved. In
addition, we have been able to better assess a person's genetic
susceptibility to specific diseases. In doing so, we have also paved
the pathway to formulate brand new drugs to treat these
diseases. In fact, drugs can essentially be custom made to
complement a person's personal biochemistry and genetic
makeup. For those diseases that were previously considered
lethal and where treatment was either non-existent or largely
unsuccessful, the discovery of DNA has essentially led to
breakthrough drugs and treatments for patients with serious
illnesses.

4. 2-Identification of genetic disorders
 People are continually sloughing off endothelial cells all
over the body. The inside of the cheek is an excellent
source to scrape off loose but still-living individual cells.
These cells can then be subjected to DNA extraction,
and a genetic assessment can be performed to look for
disorders. In a developing fetus, it's also possible to
extract a few cells from a hollow needle puncture, which
usually poses little risk to mother and child, and assess
for any genetic abnormalities, even before the fetus is
fully developed.

5. 3-Paternity and Legal Impact
 While the discovery of DNA has perhaps impacted
medicine the most, its contribution to other areas is
still similarly significant. Paternity cases have an
enormous impact on families and children around the
world. Through the assessment of DNA, the paternity
of a child can be identified, which has a significant
effect on the child's upbringing and his or her life.

6. 4-Forensics and DNA
 DNA has been notably important to the field of forensic
science. The discovery of DNA has meant that the guilt or
innocence of a person who is investigated for a crime can
be determined. It also means that scarce evidence can still
yield vital clues regarding the perpetrator of a crime. Also
important is that the identification of victims can occur,
particularly in cases where the victim's condition is
unrecognisable to family or friends. In this sense, DNA has
been important in revolutionising the entire field of
forensic science. This impact is felt within the criminal
justice system and contributes to the accurate safeguarding
of society.

7. 5-Agriculture and DNA
 The impact of DNA on agriculture has been a very
important one because it has allowed breeders to
facilitate the breeding of animals that have a better
resistance to diseases. It also allows farmers to produce
more nutritious produce, which has particularly
important consequences in developing countries
where the population subsists on a small range of
staple foods that have little variety. This means that
micronutrient deficiencies can be addressed in these
countries.

8. DNA Importance Continues
 While the discovery of DNA has been a significant one in
the twentieth century, it will continue to revolutionise
medicine, agriculture, forensics, paternity and many other
important fields in society today. DNA research
encompasses an evolving area of progress and continued
funding and interest in its relevance will likely fuel new
discoveries in the future.
