1. Warm Up for 11/30 What codes for a protein? What is a karyotype?
In your opinion, put the following words in the correct order. Be prepared to explain your reasoning.
Body
Chromosome
Cell
DNA
Gene
Nucleus

2. Karyotype Notes
11/30/15

6. Karyotype- set of chromosomes in a cell
Goes from big to small
Banding patterns match up

7. Our cells have 23 pairs
The 23rd pair is X and Y
XX=girl, XY=boy

8. Trisomy- when there’s 3 of a chromosome instead of 2
Example: Trisomy 21 is down’s syndrome

23. Exit Ticket for 11/30/15
Correctly draw the levels of organization (the same ones included in your warm up) into your IAN.
You must show me before you leave class to get credit.
