1   INET Lab Report 9 Mitosis Report Template Student:    Email :   Date:    I. Mitosis in Eukaryotes II. Cell Cycle EXERCISE 9.1  – Identify the stages of the cell cycle 1. Identify the stages of the cell cycle and list the major events of each stage. Stage Major events Interphase G1  Cytoplasmic growth S Chromosome replication G2 Spindle constructed, chromosomes condense Mitosis Prophase Chromosomes condense, nuclear envelople  dissolves, centriole pair move to opposite poles,  spindle apparatus attaches to chromosomes  Metaphase Chromosomes most condensed, chromosomes  align on the equator with the centromere exactly on  equator  Anaphase  Sister chromatids are separated from each other  and move toward the opposite poles, sister  chromatids are pulled toward poles by the spindle  apparatus Telophase  Chromosomes reach poles, nuclear envelope fprms  around chromosomes  What percent of the cell life cycle is interphase? 95 What percent of the cell life cycle is involved in nuclear division? 5 When cytokinesis is completed in the telophase stage, how many new cells enter the G 1  stage of interphase? © Access Learning Systems
