Unit 6 Cell Cycle & **Mitosis** **__Chapter 6__** a. Cell division allows organisms to reproduce asexually, grow, replace worn out or damaged tissues and form gametes. b. Bacteria reproduce through binary fission. ([|Click Here For Video]!) c. At cell division, each chromosome consists of two chromatids attached at the Centromere. d. Each organism has a characteristic number of chromosomes. ([|Click Here For Table]!) e. Human somatic cells are diploid, with 23 pairs of homologous chromosomes. Human gametes are haploid, with 23 chromosomes. ([|Click Here For Video]!) f. Sex chromosomes carry information that determines an organism’s sex. ([|Click Here For Video]!) g. Changes in chromosome number or structure can cause abnormal development. Karyotypes are used to examine and individuals chromosomes. ([|Click Here For Video]!) ([|Click Here For Video]!) ([|Click Here For Video]!) ==**2. Students will be able to identify the major events that characterize the five phases of the cell cycle **, **how it is controlled in eukaryotes and what role it plays in cancer.** ([|Click Here For Video]!) == a. The life of a eukaryotic cell, the cell cycle, includes Interphase, mitosis and Cytokinesis. b. Interphase consists of 3 phases: growth, DNA synthesis and preparation for cell division. A cell about to divide enters the mitosis and cytokinesis phases of the cell cycle. ([|Click Here For Video]!) c. The cell cycle is carefully controlled; failure of control can result in cancer. ([|Click Here For Video]!) ([|Click Here For Video]!) ==**3. Students will be able to describe the stages of mitosis. **<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">([|Click Here For Video]!) == <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">a. Prophase – Chromosomes condense, nuclear membrane dissolves, and spindles begin to move toward poles. ([|Click Here For Video]!) <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">b. Metaphase – Chromosomes line up along the middle. ([|Click Here For Video]!) <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">c. Anaphase – Spindle fibers guide chromatids to opposite sides of the cell. Nuclear membrane begins to reappear. ([|Click Here For Video]!) <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">d. Telophase – Chromosomes uncoil and spindles disappear. ([|Click Here For Video]!) ==**<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">4. Students will be able to differentiate Cytokinesis in plants and animals. **<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">([|Click Here For Video]!) == <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">a. Cytokinesis occurs in animal cells when the cell membrane pinches in half. <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">b.

Students will be able to differentiate between a gene, a DNA molecule, a chromosome, a chromatid, between homologous chromosomes, sex chromosomes and autosomes. They will be able to compare and contrast haploid and diploid cells and how changes in chromosome numbers or structures can affect development. **<span style="font-family: 'Times New Roman','serif'; font-size: 16px;">([|Click Here For Video]!) ==
