I Definitions Using your textbook define each of the following cellular stages of interphase mitosis and cytokinesis and describe the appearance of the cell and what is happening to the cellular DNA at each stage 1 Interphase II Mitosis A Prophase B Metaphase c Anaphase D Telophase III Cytokinesis Laboratory Objectives After completing this lab topic you should be able to 1 Describe the activities of chromosomes and microtubules in the cell cycle including all phases of mitosis and meiosis 2 Identify the phases of mitosis in root tip and whitefish blastula cells 4 Describe differences in mitosis and cytokinesis in plant and animal cells 5 Describe differences in mitosis and meiosis Introduction The nuclei in cells of eukaryotic organisms contain chromosomes with clusters of genes discrete units of hereditary information consisting of double stranded deoxyribonucleic acid DNA Structural proteins in the chromosomes organize the DNA and participate in DNA folding and condensation When cells divide chromosomes and genes are duplicated and passed on to daughter cells Single celled organisms divide for reproduction Multicellular organisms have reproductive cells eggs or sperm but they also have somatic body cells that divide for growth or
