ad·e·nine (A, Ade),(ad'ĕ-nēn),
AdenineOne of 2 (the other is thymine) major purine bases (C5H5N5) in nucleic acid. Adenine pairs with a pyrimidine in nucleic acids—with thymine in DNA, or with uracil in RNA; adenine combines with deoxyribose to form deoxyadenosine in DNA and ribose to form adenosine in RNA. Adenine is a major factor in a plethora of biological and molecular reactions.
ad·e·nine(A, Ade) (ad'ĕ-nēn)
adenineA purine base. One of the four key biochemical units from which genes are formed in DNA and by which the two helical halves of the DNA molecule are linked together. Adenine pairs with thymine in DNA, but in RNA it pairs with uracil.
adenine (A)one of four types of nitrogenous bases found in DNA, having the double-ring structure of a class known as PURINES (see Fig. 13 ).
Adenine forms part of a DNA unit called a NUCLEOTIDE and always forms COMPLEMENTARY BASE PAIRING with a DNA PYRIMIDINE base called THYMINE (see Fig. 14 ). When pairing with RNA during TRANSCRIPTION, adenine is complementary to URACIL. Adenine also occurs in RNA molecules, ATP, ADP and AMP.
