Introduction :
Nucleotides nucleic acids
of DNA and RNA
°
are
precursors
.
,
° Nucleotides are also
components of important co -
enzymes
like
-1
and FAD and metabolic
regulators
MAD such
, as cAMP & cGMP .
Composition :
°
3
components -
base (
( as
Nitrogenous a
purine
( bi Pentose
sugar
or a
pyrimidine)
cc , Phosphate groups
.
Bases Present in Nucleic Acids :
o Two
types of Nitrogenous base = Purines 4 Pyrimidines .
