Adenine is an organic molecule found in DNA, ribonucleic acid (known as RNA) and adenosine triphosphate, better known as ATP.
Guanine
Guanine is a purine base found in DNA and RNA that binds exclusively with cytosine to form ribonucleosides called guanosine or deoxyribose to form deoxyguanosine.
Thymine
Thymine is a pyrimidine base found in DNA that binds to adenine.
Cytosine
Cytosine is a pyramid-shaped nitrogenous base that binds to guanine in RNA and DNA as nucleotides and functions as part of the genetic code.
