Nucleic Acid
(Unit-1)
,STRUCTURE OF DNA
Nucleotides and Nucleic Acids Have Characteristic Bases and
Pentoses
Have three characteristic components:
• a nitrogenous (nitrogen-containing) base,
• a pentose, and
• a phosphate
Molecule without the phosphate group is called a nucleoside
Nitrogenous bases are derivatives of two parent compounds,
pyrimidine and purine
, N’ Bases
