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 is located mainly in the nucleus, but can also be found in other cell structures called mitochondria. Since the nucleus is so small, the DNA needs to be tightly packaged into bundles known as chromosomes.
The basic unit of DNA is a nucleotide. Each nucleotide consists of three portions: a phosphate group, a five-carbon sugar and a nitrogenous base. DNA uses four nitrogenous bases: adenine, thymine, guanine and cytosine.
DNA stands for deoxyribonucleic acid, which is the molecule that carries genetic information in humans and all other living organisms.
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 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
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.
