Nov 12, 2014 · DNA stands for deoxyribonucleic acid. DNA exists inside your body's cells and is made up of four chemicals: adenine, thymine, cytosine, and guanine. Scientists usually shorten these to simply A, T, C, and G. These chemicals that make up DNA are strung together in long, coiled strands within your cells.
DNA is the long molecule that contains your unique genetic code. A bit like a recipe book, it holds the instructions your cells need to make all the proteins in your body. Your genome is the complete set of instructions your body needs to function. It’s made of a long molecule called deoxyribonucleic acid, or DNA for short.
Apr 11, 2023 · DNA stands for deoxyribonucleic acid. It is a long, chain like chemical made of many links. Each link is called a nucleotide. Each nucleotide is composed of 3 molecules: A sugar called deoxyribose. A phosphate. One of the four nitrogen bases - Adenine, Thymine, Guanine and Cytosine. The length of the DNA depends on the number of nucleotides in it.
Oct 21, 2022 · Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. Stanislaw Pytel/Getty Images.
Key terms. DNA structure. DNA is a nucleic acid, one of the four major groups of biological macromolecules. Nucleotides. All nucleic acids are made up of nucleotides. In DNA, each nucleotide is made up of three parts: a 5-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.
DNA, or deoxyribonucleic acid, is the molecular basis for inheritance, discovered in the mid-1800s and understood in 1953 with the double helix structure. Composed of a sugar-phosphate backbone and base pairs (adenine-thymine, guanine-cytosine), DNA stores genetic information, replicates, and expresses traits.
