Adenine always pairs with thymine when forming chains of DNA. In RNA, a similar molecule to DNA that is also used to encode genetic information, adenine always pairs with uracil. More »

The base pairs in DNA are adenine to thymine and guanine to cytosine. In RNA, they are adenine to uracil and guanine to cytosine. More »

DNA is a stable, double helix that functions in long-term storage of genetic material, while RNA is a reactive, single helix that transfers information. There are also slight differences in base pairs between DNA and RNA... More » Science Biology Molecular Biology & DNA

The four types of nucleotides found in DNA are guanine, cytosine, adenine and thymine. These are nitrogenous bases and are subdivided into purines and pyrimidines. The purines are adenine and guanine, and the pyrimidines... More »

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... More »

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 ... More »

The complementary base pairing rule states that in DNA, adenine always pairs with thymine and guanine pairs with cytosine. This rule ensures that DNA is replicated faithfully and mutations are minimal occurrences. More » Science Biology Molecular Biology & DNA
