[DNA](http://en.wikipedia.org/wiki/DNA) tells you how to make RNA which tells you how to make Proteins.

----
1. DNA Replication
2. Transcription
3. Translation

----
Each half of the DNA ladder can be reproduced from the other half. They are a mirror image of one another.

----
mRNA represents a particular gene

----
mRNA through translation makes a protein

----
a protein is a chain of amino acids

----
about half of the amino acids cannot be constructed and must be consumed through food

----
amino acids are the building blocks of proteins 

----
amino acids can chain together

----
every amino acid maps to a sequence of three base pairs in the RNA

----
every triple in the RNA defines what amino acid goes next in the protein
