PPT-Control of the Cell Cycle

Unit 1 Cells and Proteins Advanced Higher Biology Miss Aitken Why is controlling the cycle important Complex events must work perfectly to produce new daughter cells Mutations can occur if events do not go to plan. Cell Increase and Decrease. Cell division increases the number of somatic cells. Consists of mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm). Apoptosis, programmed cell death, decreases the number of cells. Section 5.1. 1. Objectives. SWBAT describe the stages of the cell cycle.. SWBAT compare rates of division in different types of cells.. SWBAT identify factors that limit cell size.. 2. Starter. Why do you always have to cut your hair, your fingernails, and the lawn?. Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . simpler. Ex: the flu. A virus with this type of cycle makes you sick right away. What about the other type of life cycle?. The . Lysogenic. Cycle.

Ways in which the normal cell cycle is disrupted to cause cancer. . Concept 9.3: The eukaryotic cell cycle is regulated by a molecular control system. La gamme de thé MORPHEE vise toute générations recherchant le sommeil paisible tant désiré et non procuré par tout types de médicaments. Essentiellement composé de feuille de morphine, ce thé vous assurera d’un rétablissement digne d’un voyage sur . Cell . Growth Limitations. Surface area: Volume. Asexual vs Sexual Reproduction. Prokaryotic vs. Eukaryotic Cell Cycle. Binary Fission vs Interphase and Mitotic Phase. DNA, Chromosomes, Chromatin, Chromatids, Nucleosomes, Histones, Centromeres, Spindle, Centrioles, Parent/ Daughter cells. Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. The cell cycle, or cell-division cycle, is the series of events that takes place in a cell leading to its division and duplication (replication). . In cells without a nucleus (prokaryotes), the cell cycle occurs via a process termed . Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. Variation of length of cell cycle. In humans, the frequency of cell turnover . varies.
