Two vocabulary Words: Mitosis Interphase Monday January 23, 2017 Day 2 1. Please have these Items on your desk. Agenda Science Starters Sheet AR Book Two vocabulary Words: Mitosis Interphase Science Notebook Monday January 23, 2017 Day 2

Definitions Mitosis-The process of the cell nucleus dividing to form 2 identical cells. Interphase- First step in Mitosis/Meiosis. Chromosomes are extended and not visible. Chromosomes replicate. Centrioles replicate.

To do list . . . Finish notes on Mitosis Work on Mitosis worksheet(HW if not completed in class)

Metaphase 2nd step in Mitosis Chromatids (or pairs of chromosomes) attach to the spindle fibers. They line up in the middle. Centrioles Spindle fibers

Anaphase 3rd step in Mitosis Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers

Telophase 4th step in Mitosis Two new nuclei form. Chromosomes appear as chromatin (threads rather than rods). Mitosis ends. Cleaving begins. Nuclei Nuclei Chromatin

Cytokinesis-occurs after mitosis Cell membrane moves inward to create two daughter cells each with its own nucleus with identical chromosomes.
