1. Nucleic Acids Structure
Elements: Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), and Phosphorus (P)
Monomer
Nucleotide
3 Parts:
Phosphate
Base
Sugar
PBS

2. Nucleic Acids
Examples:
DNA & RNA

3. Nucleic Acids
DNA is antiparallel – the 2 strands are parallel, but opposite
5’ End has the Phosphate group; 3’ End has the OH
One strand goes 5’-3’ & the other strand goes 3’-5’
A bonds with T (and U for RNA)
C bonds with G
Covalent bonds are strong
Hydrogen bonds are weak

4. Nucleic Acids
Function DNA contains the genetic information RNA makes protein

5. DNA is double stranded; RNA is single stranded
Nucleic Acids
DNA vs RNA
DNA is double stranded; RNA is single stranded

6. Nucleic Acids
Since we eat organisms, we are eating cells along with that cell’s DNA
Our body breaks down the cells & their DNA
The components (atoms) are recycled, & our body uses them to build our own DNA
