DNA, or deoxyribonucleic acid, is used in the human body in order for an organism to reproduce, develop and survive as well as in science for genetic engineering, forensics, bioinformatics, evolutionary history and information storage. A human's DNA code contains about 3 billion bases and 20,000 gen


The majority of DNA is located in the cell nucleus, where it is called nuclear DNA. A small amount is located in the mitochondria, where it is called mitochondrial DNA.


DNA is made of repeating units called nucleotides. The four nucleotides in DNA are adenine, cytosine, guanine and thymine. Adenine binds with thymine, and guanine binds with cytosine.


DNA works by storing information that tells the body how to develop, survive and reproduce cells. DNA sequences are made up of four types of nucleotides: adenine, thymine, cytosine and guanine. Information in DNA is stored by the ordering of bonded nucleotides and resides in pieces of DNA called gen


DNA stands for deoxyribonucleic acid, which is the molecule that carries genetic information in humans and all other living organisms.


DNA is often referred to as the blueprint for life because all living organisms have DNA, including plants. DNA stores the genetic information that links every organism to a common ancestry. Some plants, such as onions and tomatoes, have more DNA than humans.


The primary function of DNA is to send the instructions needed for the development, survival and reproduction of living organisms. DNA contains information required to create proteins, and proteins are used to complete specific functions. Proteins are complex molecules that serve different functions


One way to make the complicated details of DNA structure and function intelligible for children is to compare it to a recipe book. DNA is the master molecule that contains coded instructions for "cooking" the proteins used by living bodies.


The sugar found in deoxyribonucleic acid, or DNA, is deoxyribose. It is a variant of the five-carbon sugar called ribose. DNA is an informational molecule found mainly in the nucleus of the cell.


Deoxyribonucleic acid was first isolated in 1869 by Friedrich Miescher. DNA is a molecule composed of long protein nucleotide chains. Each nucleotide is further composed of the nucleic acids adenine, guanine, cytosine or thymine. Between these nucleic acids, adenine pairs with thymine, and cytosine
