Crafty Chromosomes

• Cell Theory
• DNA
• Genes
• Chromosomes
• Sister chromatids
• Centromere
• Homologous chromosomes

2
The cell cycle

• Cell cycle
• G1
• S
• G2
• Mitotic phase

3
Whats the purpose of mitosis?
4
Magnificent Mitosos!

• IPMAT
• interphase
• prophase
• metaphase
• anaphase
• telophase

5
Interphase

• High metabolic activity
• G1
• S
• DNA sythesis
• G2

6
Prophase

• What happens to the chromatin?
• What happens to the nucleolus?
• Sister chromatids, centromere
• What happens to the nuclear envelope (membrane)?

7
Metaphase

• Meet in the middle
• spindle microtubules
• centrioles
• homologous pairs meet at the equator of the cell

8
Anaphase

• Sister chromatids separate and move to opposite
  poles (now called chromosomes)
• spindle microtubules
• centrioles

9
Telophase and Cytokinesis

• Reverse of prophase
• chromatin
• nucleoli
• nuclear envelope
• Cytokinesis

10
Cancer

• Cancer cells
• Benign tumor
• Malignant tumor
• metastasis
