Nucleic acid
Nucleic acids are molecules that store information for cellular growth and reproduction.
Nucleic acids are polymers of nucleotides.
Nucleotides are carbon ring structures containing nitrogen linked to a 5-carbon sugar and a phosphate group.
History
Firstly it is called nuclein because it is isolated from the nuclei of pus cells.
Nuclein was shown to have acidic properties, hence it became called nucleic acid.
Nucleic acid structure
Nucleic acid are polynucleotides.
Their building blocks are nucleotides.
All nucleotides contain three components A nitrogen base
A pentose sugar
A phosphate group
