Definitions of B DNA

  1.   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
