The Importance of DNA

Dna Discoveries Forensic Science

It has been argued that the discovery of DNA as well as our understanding of its structure and functioning may well be the most important discovery of the last century. The effect of the discovery of DNA on scientific and medical progress has been enormous, whether it involves the identification of our genes that trigger major diseases or the creation and manufacture of drugs to treat these devastating diseases. In fact, the identification of these genes and their subsequent analysis in terms of therapeutic treatment has ultimately influenced science and will continue to do so in the future.

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.

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.

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.

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.

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.

Do DNA codes got anything to do with luck?

I have been studying the process of cell division and DNA replication. In explanations of those processes it is always noted that one of the first steps in cell division is the replication of the DNA molecule. But at that point the DNA molecule is wrapped up tightly in the chromosome so it is not clear how the DNA can replicate. Yet those explanations proceed by stating the DNA replication is first before cell division. I have never come across any explanation which indicated that either the chromosome unwinds to allow DNA replication or perhaps notes another path to the DNA replication. If you could offer an explanation to me or lend some directions in which I can search, that would be much appreciated.

The page was do helpful in offering some basics on the basis of heredity factors for genetic make up of cells which are the basic units of life

Even thought DNA is needed it sure is a bother to deal with even if ti is not to taken lightly.

so iv'e really enjoyed your information on the importance if DNA and is really showing me the importance of how we ourselves can stay healthy and our bodies keep our bodies healthy.

Why is it important that we discovered the structure of DNA? How do we use it today?

James Watson and Francis Crick made the discovery of dna and made the first model of dna.

Why was it so important that Rosalind Franklin made the discovery of DNA?And how did it impact us?
Trin-Trin - 31-Oct-13 @ 8:28 PM
we use DNA to find out who committed the crime all DNA is on file somewhere but you never know when the police can get their hands on it.

I want the use of DNA to be popular in Nigeria so that criminal acts will be reduced
babygold - 29-May-13 @ 7:49 AM
we try to extract DNA from the scene and also get DNA from various suspect. the electrophoresis of those DNA are carried out the DNA that move at the same speed with the one extracted from the scene is the offender.
best future - 11-Oct-12 @ 3:52 PM
How can we use DNA to detect the person that actually committed the crime. How reliable is DNA result to crime detection.
