DNA Structure and Replication

Outline  DNA Structure Nitrogenous Bases Nucleotides  DNA Replication Semi Conservative Enzymes

Remember the nitrogenous bases?

What is a Nucleotide?

DNA Structure…YOU TRY!!! Using your nucleotides, try and figure out how DNA is put together!

Watson and Crick Model

Why DNA replication?

DNA Replication

 Semi-conservative

What Makes Replication Happen? 1. Helicase Helicase unzips the DNA at the REPLICATION FORK

What Makes Replication Happen? 2. DNA Polymerase DNA Polymerase adds nucleotides to make new DNA

Eukaryotes Prokaryotes
