Nucleic acids:
A complex biomolecule that
stores cellular information in the
form of a code
2006-2007
Contain elements:
Carbon, Hydrogen,
Oxygen, Nitrogen,
Phosphorous
Functions (uses):
• Store and transmit genetic information
• Contain “instructions” used to create
organisms’ enzymes/protein
• Monomer subunits of nucleic acids are
nucleotides
– Nucleotides= a. nitrogenous base
– Sugar
– Phosphate group
• Nitrogenous base + sugar + phosphate group =
nucleotide
• Nucleotide + nucleotide + nucleotide +…. =
Nucleic Acid
Nucleic Acids
Examples
– DNA
• Double strand,
contain “directions”
for inheritance;
sugar
deoxyribose
– RNA
• Single strand, help
encode info for
making proteins;
sugar ribose
