1 Nucleic Acids

2 Nucleic Acid Basics Contain instructions to build proteins 2 types:
DNA RNA Composed of smaller units called nucleotides Monomer: Nucleotide Polymer: Nucleic acid

3 Nucleotide Structure Three parts
Sugar molecule Phosphate group Nitrogen base (1 of 4 types) Nitrogen Base arrangement determines protein created

4 Monomers link to make polymers
Monomers link to make polymers! Nucleic Acids Monomer = Nucleotide Polymer = Nucleic acid



7 DNA Double Helix: 2 chains of nucleotides
DNA bases: Adenine, thymine, cytosine, guanine A pairs with T C pairs with G DNA stores the info required to make a protein Gene: section of DNA that codes for a protein

8 Nucleotides? How many

9 RNA 1 chain of nucleotides
RNA bases: Adenine, uracil, cytosine, guanine Copy the DNA code… deliver code to ribosome to make a protein
