1. DNA Notes The Genetic Code A. Genes and DNA B. Order of the Bases
* Main fnctn of genes is to make proteins which determine traits ( eye color etc)
A. Genes and DNA
* A gene is part of the DNA that has info for one protein
* ATGC are the nitrogen bases
B. Order of the Bases
* The order of the bases ( ATGC) form the genetic code
* 3 Bases ( CGA) = amino acid

2. II. How Cells Make Proteins
The gene has the info. to make a protein
Proteins are made in the ribosomes ( in the cytoplasm)
A. The Role of RNA
RNA = Ribonucleic Acid
RNA = one strand
RNA = U instead of T
B. Types of RNA
mRNA – delivers DNA’s message to the ribosome
tRNA – Picks up amino acids and adds them to the protein chain.

3. III. Mutations A mutation is a change in a gene or chromosome
It makes the cell make the wrong protein
A. Types of Mutations
Wrong pair combo ( A-C)
Chromosomes don’t separate
A piece of a chromo. Stuck on
Bases missing
B. Effects of Mutations
Can be helpful, harmful, or nothing
Sometimes the environment dictates
