Definition
English
:
A deoxyribonucleotide
polymer
that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of
purines
(
adenine
and
guanine
) and
pyrimidines
(
thymine
and
cytosine
), forms a double helix that is held together by
hydrogen
bonds between these
purines
and
pyrimidines
(
adenine
to
thymine
and
guanine
to
cytosine
).
