Season 1: DNA and Chromosomes
Episode 5: Chromosome Structure
Objective: Create a model to show the relationship between DNA and Chromosomes
Bell Ringer: Get out your notebook and prepare for notes! Gwahaha!

2. Structure of Chromosomes

3. DNA

4. DNA
DNA is the genetic material that codes for you

5. DNA
DNA is the genetic material that codes for you
A section of DNA codes for a gene

6. DNA must be loose during interphase in order to be read

7. Chromosomes

8. Chromosomes
Chromosomes are made of DNA and histones (proteins)

9. Chromosomes
Chromosomes are made of DNA and histones (proteins)
The DNA wrapped around the histones is called chromatin

10. The chromatin then condenses to create a chromatid

11. The chromatin then condenses to create a chromatid
A duplicated chromosome is made of two chromatids held together by a centromere

12. DNA condenses into chromosomes during mitosis and meiosis

13. DNA condenses into chromosomes during mitosis and meiosis
The condensed package allows the DNA to be evenly divided between the new cells.
