DNA is a long molecule composed of two chains of smaller molecules called nucleotides, each which contain a region of nitrogen called the nitrogenous base, a carbon-based sugar molecule called deoxyribose and a region of phosphorus called the phosphate group. There are four types of nitrogenous base


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


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.


The backbone of the DNA molecule is made of a repeated pattern containing a sugar called deoxyribose and a phosphate group. The backbone is spatially arranged in the form of a double helix, with base pairs connecting the two sugar-phosphate strands.


DNA, or deoxyribonucleic acid, is a chain that is made up of smaller parts known as nucleotides. These nucleotides are then made up of three different parts of nucleotides: the sugar group, the phosphate group and a group of four different nitrogen bases, which are adenine (A), cytosine (C), guanine


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


A double helix, or a twisted-ladder shape, is the standard structure of DNA. It consists of two strands of a sugar-phosphate backbone and the nucleotide base pairs adenine, thymine, guanine and cytosine. Adenine pairs with thymine, and guanine pairs with cytosine by non-covalent hydrogen bonds.


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 purpose of DNA is to store hereditary information within the cells of all living things. It is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms.
