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

Nucleic Acids Examples: DNA & RNA

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

Nucleic Acids Function DNA contains the genetic information RNA makes protein

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

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

Show What You Know: Nucleic Acids What elements make up a nucleic acid? 2. What is the monomer for a nucleic acid? What are the 3 parts of a nucleotide? 4. List 3 differences between DNA & RNA.
