PPT-MITOSIS

The Only Time When Division and Multiplication Will Mean The Same Thing The Life of a Cell All cells in your body alternate between two different activities Interphase the cell is doing the job it was meant to do andor preparing for cell division. Unit 5. Welcome Back! . Musical Chairs. TODAY:. Notes on Cell Cycle. Become medical school students on oncology . rotation. Homework for next time: Watch Bozeman video on cell cycle, mitosis and meiosis. There *may* be a quiz.. Cytokinesis. 01-08-09. http://www.cellsalive.com/mitosis.htm. Cell Division. The division of eukaryotic cells occurs in two main stages. Mitosis is the first stage. Is the process by which the nucleus of the cell is divided into two nuclei, each with the same number and kinds of chromosomes as the parent cell. Be sure to turn in any labs from yesterday. . . Today . we will be discussing:. Mitosis. Every minute your body needs to make 300 MILLION new cells!!. Your DNA carries all the instructions for the cell, including when to do mitosis. Yvonne Norman. Edited By: . Ms. . Ethridge. , Ms. Myers, Ms. . Milstead. , and Ms. Palermo. Objectives. Define mitosis.. Define meiosis.. Analyze function of mitosis and meiosis in cell differentiation.. A Chromosome and Sister Chromatids. Key Points About Chromosome Structure. A . chromosome consists of DNA that is wrapped around proteins (. histones. ) and condensed. Each . histone. and the DNA wrapped around it make up a . Section 5.2. 1. Objectives. SWBAT describe the structure of a chromosome.. SWBAT follow chromosomes through the processes of mitosis and cytokinesis.. 2. Vocabulary. Chromosome. Histone. Chromatin. Chromatid. Parts of the Human Cheek Cell at 40X Magnification. Can you name these parts of the Human Cheek Cell?. CELL CYCLE. D. uring Interphase DNA replicates which must occur before Mitosis can begin .. Centrioles.

Figure 9.1 – Chromosomes during cell division. Chromatin – the less tightly coiled DNA-protein complex. Centromere – the region of the chromosome that holds the two sister chromatids together during mitosis.. SEX CHROMOSOMES & AUTOSOMES. Sex chromosomes are chromosomes that determine the sex of an organism, and they may also carry genes for other characteristics. . KEY CONCEPT . Cells divide during mitosis and cytokinesis.. Show biology presentation film . clip mitosis 2. Chromosomes condense . at . the start of mitosis.. DNA wraps around proteins (histones) that condense it.. The . cell cycle. is a repeated pattern of growth and division that occurs in eukaryotic cells. . This cycle consists of three phases: G1, S, G2. The first phase represents cell growth while the last two phases represent cell division.. . Cell Division Video Clip. Learning Goal: SWBAT describe and model the steps of mitosis. Scale of Understanding. Rate yourself on your level of understanding of mitosis-mark this on your sheet:. 4. ANA 205. 2. Differentiation. - development of a fertilized egg cell to form a complex, multicellular organism involving cellular replication, growth and progressive specialization for a variety of functions. . Levels of Biological organization. Cells  Tissues. Tissues  Organs. Organs  Organ Systems. Organ Systems  Organisms . From zygote to Trillions of Cells. Zygote=Cell that forms when sperm and egg join.
