How Cells Divide Chapter 10
Bacterial Cell DivisionBinary Fission FtsZ protein
Eukaryotic ChromosomesChromosome Numbers Vary Made of Chromatin
Some Vocab Karyotype Haploid Diploid Homologue Chromatids
Overview of the Cell CycleG1 S G2 M C G0
Interphase G1, S, G2
Mitosis Prophase Prometaphase Metaphase Anaphase Telophase
Prophase Condensation of Chromosome Contintues Spindle apparatusAsters Nuclear envelope disassembles
Prometaphase Micrtubules attach to the kinetochoreChromosomes begin to move toward the equator of the cell
Metaphase Chromosomes are aligned at the equator of the cell called the metaphase plate Chromosomes are attached to opposite poles and are under tension
Anaphase Proteins holding centromeres of sister chromatids are degraded, freeing individual chromosomes Chromosomes are pulled to opposite poles Spindle poles move apart
Telophase Chromosomes are clustered at opposite poles and decondenseNuclear envelopes reform around chromosomes Golgi complex and ER re-form
Cytokinesis Plant vs Animal
Control of the Cell CycleIrreversible points Checkpoints
MPF Nondividing cells can be stimulated into division by MPFMPF activity changes throughout the cell cycle It is cyclin pluc cdc2 (aka Cdk) What is a kinase?
Three main CheckpointsG1/S G2/M Spindle Checkpoint (APC) Figure 10.20
Growth Factors Trigger intracellular signaling systemsRTKs and MAP cascades
G0 Phase Dormant Liver vs Intestinal Lining Cells
Cancer Tumor Suppressor genes- p53, Rb Oncognes-ProtoOncogenes

Mitosis n Mitosis is the process by which new cells are generated. n Mitosis produces 2 genetically identical daughter cells.
