Scribe for 12/13

Today we started off the class with discussing the homework that was due today well Lucky for you Unit packet pages 73-74 got moved to tomorrow so go over them at home so your prepared to talk about them tomorrow. Then we reviewed the Karyotyping Web Quest in which you're gonna have to know:

1. How to see a disorder by only looking at the karyotype.
2. Determine what that disorder is.
3. Also to determine what chromosome it's on and how it effects that chromosome

Here are two examples of a Disorder:

Turner Syndrome

1. Only one X chromosome on woman
2. On karyotype you can see that there is only one X chromosome

Down Syndrome

1. Has one extra copy of chromosome 21
2. On Karyotype look for three chromosomes on 21

Then we started taking notes on Genetic Engineering is when you practically copy and paste genes. You Manipulate DNA into ways that are useful to you. We also learned About PCR or Polymerase Chain Reaction is when you use Polymerase to make more DNA. We then learned about Restriction Enzymes and those are enzymes that precisly cut and recognize a certain base sequence. We then finished off class with a nice movie on how Forensics use DNA to capture suspects.
