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...
Without DNA, life would not be able to perpetuate itself. DNA is needed as it is the blueprint of life. Every species of plants and animals contains a genetic substance called DNA that passes on the physical characterist...
DNA and RNA are nucleic acids, which are also considered polymers. Deoxyribonucleic acid is used to create ribonucleic acid that, in turn, contains the primary sequence of amino acids needed to make proteins.
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.
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.
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 ...
