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
