DNA stores information in a sequence of adenine, cytosine, guanine and thymine on a backbone of two deoxyribose molecules, which intertwine in a double helix. In nature, this information is read by RNA molecules and turn...
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 orga...
DNA stands for deoxyribonucleic acid, which is the molecule that carries genetic information in humans and all other living organisms.
The base pairing rules for DNA are governed by the complementary base pairs: adenine (A) with thymine (T) in an A-T pairing and cytosine (C) with guanine (G) in a C-G pairing. Conversely, thymine only binds with adenine ...
Adenine, guanine, cytosine and thymine are the four chemical bases found in DNA. In a given DNA molecule, adenine always pairs with thymine, and guanine always pairs with cytosine.
The rungs of the DNA ladder consist of four nitrogenous bases: adenine, thymine, cytosine and guanine. Each rung of the ladder is composed of two of the nitrogenous bases held together by hydrogen bonds.
Nitrogenous bases are the class of biological molecule to which guanine, adenine, cytosine and thymine belong. These nitrogenous bases combine with a five-carbon sugar and a phosphate group to form nucleic acids such as ...
