What is DNA?
DNA stands for deoxyribonucleic acid.
Carries the genetic code.
DNA
Adenine (A)
guanine (G)
cytosine (C)
thymine (T).
A goes with T and C goes with G.
Adenine
• Adenine is an integral part of DNA,
RNA, and ATP.
• Formula: C5H5N5
• Molar Mass: 135.13 g/mol
• Density: 1.60 g/cm
Guanine
What is guanine?
Guanine is a purine base, C 5 H 5 N 5 O, that is a
fundamental constituent of DNA

Cytosine
What is cytosine?
Cytosine is A pyrimidine base,
C4H5N3O, that is the constituent of DNA
and RNA involved in base-pairing with
guanine.
