Chapter 28: Nucleosides, Nucleotides and Nucleic Acids
Summary
Nucleic acids
are the acids found in cell nuclei and are involved in the transmission of genetic information.
They are complex biopolymers containing a
carbohydrate
, a
phosphate ester
and a
heterocyclic aromatic unit
, the
base
.
There are two types of nucleic acids :
ribonucleic acids
or
RNA
, and
deoxyribonucleic acid
or
DNA
.
