DIAGNOSTIC IMPORTANCE of DNA &

RNA EXTRACTION

Why DNA is important_.mp4

1-Disease Diagnosis and TreatmentOne 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.

DIAGNOSTIC IMPORTANT

2-Identification of genetic disordersPeople 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.

DIAGNOSTIC IMPORTANT3-Paternity and Legal ImpactWhile 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.

DIAGNOSTIC IMPORTANT4-Forensics and DNADNA 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.

DIAGNOSTIC IMPORTANT5-Agriculture and DNAThe 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.

DIAGNOSTIC IMPORTANTDNA Importance ContinuesWhile 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.
