Organic compounds
• Contain carbon• Were once part of a living thing
Atoms in these molecules are held together by covalent bonds
Four major types• Carbohydrates• Lipids• Proteins• Nucleic acids
Nucleic Acid
Nucleic Acids• Contain C, H, O, N, and P• Building blocks: nucleotides
SugarPhosphateNitrogen base
• 2 types: DNA & RNA
• Function: Nucleic Acids Contain our genetic information

Nucleic Acid
DNA‐Deoxyribonucleic AcidDouble helix in which 2 strands are wound around each other
Each strand is made up of a chain of nucleotides (5carbon sugar [deoxyribose], phosphate group, and a nitrogenous base)
Stays in the nucleus
4 Kinds of Nitrogen Bases:AdenineGuanineCytosineThymine
Nucleic Acid
DNA‐Deoxyribonucleic AcidHydrogen bonds hold nitrogenous bases together in the center of the double helix: (base pairing)
Adenine binds with ThymineGuanine binds with Cytosine
