Meiosis I: Replication
Interphase I DNA Replication Chromatin a “ball of yarn”
Prophase I Chromosomes coil and condense Form a tetrad (synapsis)
Metaphase I Tetrads align along equator
Anaphase I Tetrads split Form dyads Dyads move to opposite poles
Telophase I Cleavage furrow forms Cell splits (cytokinesis)Form two diploid daughter cells
Meiosis II: Reduction Division
Interkinesis Similar to Interphase I No DNA replication
Prophase II Chromosomes condense and coil
Metaphase II Chromosomes align along equator
Anaphase II Dyads split at centromereChromatids move to opposite poles
Telophase II Cleavage furrow forms Cell splits Both diploidForms 4 haploid daughter cells
Cell Cycle IPMATC.
The Cell Cycle.
11-4 Meiosis Pg. 275.
Cell Division Lab 10.
Aim: Why is meiosis important?
The Other Cell Division: Making Sex Cells
Meiosis Honors Biology Spring 2013.
Chromosomes and Cell Reproduction Objectives: 1.Identify different types of cell division 2.Differentiate between a gene, a DNA molecule, a chromosome,
Mitosis and the Cell Cycle Division of the nucleus and the nuclear material (DNA), as well as the cell.
Cell Division pg. 67 Cell life cycle - changes a cell goes through from when formed to division 1.Interphase - cell grows, metabolic activities 2.Cell.
Cell Reproduction in Bacteria Binary Fission: asexual reproduction producing genetically identical cells.
