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

Karyotype Notes 11/30/15

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

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

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

Picture of Chromosomes = Karyotype
