1. EXTRACTION AND FINGERPRINTING DNA

2. The Genetic Code Genes- control the production of proteins in an organisms cells. Proteins determine the traits of an organism

3. DNA DNA is made of four nitrogen bases  A (adenine)  T (thymine)  G (guanine)  C (cytosine) They form the rungs of the DNA ladder.

4. Nitrogen Base Pairs The bases A, T, G, C pair up in certain ways. A with T G with C These are called- Base Pairs Each human cell has 3 billion DNA base pairs.

5. DNA and Proteins The order of the nitrogen bases creates the genetic code. The genetic code determines what protein will be produced. Much of the code is not used. http://www.pbs.org/wg bh/nova/genome/dna_f lash.html http://www.pbs.org/wg bh/nova/genome/dna_f lash.html

6. DNA Extraction Taking DNA out of a cell to read the code. http://learn.genetics.utah.edu/content/labs/extracti on/ http://learn.genetics.utah.edu/content/labs/extracti on/

7. DNA fingerprinting Everyone’s genetic code is different just like fingerprints. (Except Identical Twins) http://learn.genetics.utah.edu/content/labs/gel/
