What is DNA and why is it important?

Answer 1

DNA is important in Biology because it's what makes us the way we are. it contains information on how we are to be made (our limbs, our hormone release, our eye colour etc) and tells each cells what their job is and what to do (it's like a brain of the cell)

Answer 2

Deoxyribonucleic acid (DNA) is a nucleic acid also it is a hereditary material that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses.

Biologically, DNA is essential to life. And also it is responsible for inheritance. It's found in all humans and all other organisms, in every cell, and stores complex information about the way we are, inherited from our parents. What this means is that DNA is absolutely unique and individual, which is perfect for determining factual circumstances in a number of cases. Through testing DNA, relationships of parentage can be easily established as can siblingship and even more distant family relationships. It can also help establish where two specimens of DNA match, thus allowing identification of the same DNA profile to be made for legal reasons.

Whilst DNA is important biologically, it is also becoming an increasing factor in our everyday lives, with Immigration processes, the police and the judicial system all relying on formal DNA testing as part of their fact-finding procedures. Whilst the results from DNA testing are not exactly conclusive of the facts, they do provide one of the best and most reliable guarantees of accurate, positive identification.

Answer 3

DNA is like the "blue prints" of a person. Almost everything that happens in your body is based on DNA. It could be used to identify people. It could be used to find out if someone is someone's child, parent or other relative. It is often used to solve crimes. A hair or blood found on the crime scene could match the DNA sample of a suspect who is claiming he's never been at the scene. It could also be used to find genetic diseases.

Answer 4

DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all living organisms. It is important because it carries the hereditary information that is passed from parent to offspring, determining traits such as physical appearance, behavior, and susceptibility to diseases. DNA also plays a crucial role in protein synthesis and overall cellular function.

Answer 5

DNA is our hereditary material which codes for all the proteins which function in our body. Our existence is determined by DNA and hence it is important to know about DNA and its functions.
