The specific
association between two complementary strands of
nucleic acids that results from the formation of hydrogen bonds between the base components of
the
nucleotides of each strand: A=T and G=C in
DNA, A=U and G=C (and sometimes G=U) in
RNA (the lines indicate the number of hydrogen bonds). Single-stranded nucleic acid molecules
can adopt a partially double-stranded structure through intrastrand base pairing.
