CELL DIVISION MEISOIS MITOSIS Interphase Stages of mitosis: Prophase Metaphase Anaphase Telophase Interphase Stagesof meiosis: Prophase l Metaphase l Anaphase l Telophase l Prophase ll Metaphase ll Anaphase ll Telophase ll
Interphase G 1 PHASE: The cell grows by producing proteins and organelles. S PHASE: DNA synthesis G 2 PHASE: The cell makes final preparations for division.
Prophase Nucleoli dissapear Chromatin fibers coil up to form chromosomes Spindle fibers are formed and attached to the centromeres of chromosomes Nuclear envelope breaks
Metaphase Spindle fibers are fully formed Chromosomes are arranged in a line on an imaginary plane (metaphase plate= ekvator düzlemi)
Anaphase Centromeres of each chromosome come apart and sister chromatids are seperated Spindle fibers pull sister chromatids towards opposite poles of the cell
Telophase Nuclear envelopes form around identical sets of chromosomes at the two poles of the cell The chromosomes uncoil Nucleoli reappear Meanwhile cytokinesis begins
Stages of Mitosis
Cytokinesis in animal cell (by cleavage furrow) Cytokinesis in plant cell (by cell plate)
The Cell Cycle & Cell Division
The Cell Cycle.
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:
Mitosis and the Cell Cycle Division of the nucleus and the nuclear material (DNA), as well as the cell.
Cells divide during mitosis and cytokinesis. Cells that make up the “body” of an organism 2.
Cell Division Mitosis & Cytokinesis. Cell Division = Mitosis During life, we go from one cell to ~ 75 trillion cells. Mitosis= process of division.

Cell Division B-2.6 Summarize the characteristics of the cell cycle: interphase (called G1, S, G2); the phases of mitosis (called prophase, metaphase,
The cell cycle and mitosis
Cell Cycle Cell division is the basis of reproduction for every organism. It also replaces worn-out or damaged cells. CELL CYCLE – an ordered sequence.
MITOSIS the key to growth.
MITOSIS. Animated Cycle
5.2 Mitosis Describe Interphase Know the phases of mitosis Know Cytokinesis.
Stages of Mitosis. Mitosis (M Phase) The M Phase consists of: Mitosis and Cytokinesis Four Stages of Mitosis: P rophase M etaphase A naphase T elophase.
Chromosomes Diploid: contains 2 sets of chromosomes Body cells, 2n Haploid: contains 1 set of chromosomes Gametes, sex cells, n Sister chromatids-
The cell cycle: interphase, mitosis, cytokinesis.
3/6/2016 Cell Division Cell divides into two daughter cells.
Cell Division Mitosis. Chromosomes Eukaryotes Found in the nucleus Contain most of the genes Made up of two sister chromatids, joined by a centromere.
