Two Parts of Cell Division(1) Mitosis – (2) Cytokinesis
The Cell Cycle Cell Cycle – series of events that cells go through as they grow and divide During the cell cycle, cells: Grow Prepare for division Divide to form two daughter cells
Cell Cycle Cont. The cell cycle consists of four phases: M PhaseS Phase G1 Phase G2 Phase
Events of the Cell CycleInterphase – period of the cell cycle between cell divisions – preparation for Mitosis Not considered mitosis!! Includes G1, S, and G2 phases G1 Phase – S – G2 –
Mitosis (4 Phases) Prophase Longest phase of mitosisChromosomes become visible and coil tightly Spindle fibers form Nuclear envelope breaks down Nucleolus disappears Centrioles migrate to opposite sides of nucleus
Metaphase 2nd Phase of mitosis Lasts only a few minutesChromosomes line up in the middle of the cell Microtubules (spindle fibers) connect centromere of each chromosome to spindle
Anaphase 3rd phase of mitosisCentromeres split – allowing sister chromatids to separate and become individual chromosomes Chromosomes separate and approach the poles of the spindle (opposite ends of the cell)
Telophase Final stage of mitosisChromosomes disperse into a tangle of dense material Nuclear envelope reforms around chromosomes Spindle fibers break apart and nucleolus becomes visible
Cytokinesis Cytokinesis – division of the cytoplasm Completes M phaseThe cytoplasm is pinched into equal parts Each new part contains its own nucleus and organelles

10-2 Cell Division.
10.2 The Process of Cell Division
The Cell Cycle and Mitosis
What’s happening and where are things moving to?
CELL GROWTH AND DIVISION CELL DIVISION. Every cell must copy its genetic information before cell division takes place. Each daughter cell then gets a.
Chapter Chromosomes are not visible in cells until cells begin the process of cell division. Chromosomes are not visible in cells until cells begin.
10 – 2 Cell Division Mitosis. Chromosomes DNA is passed on in chromosomes DNA is passed on in chromosomes Every organism has a specific # of chromosomes:
The Process of Cell Division
Chapter 9: Chromosomes and Mitosis p Review of Important Terms: Gene - segment of DNA that codes for a protein Chromosome - DNA + proteins,
Mitosis. Common to most living things Sequence of growth and division of a cell.
