PPT-Mitosis and Cytokinesis

Section 52 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. 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 and/or preparing for cell division.. The cell cycle. Mitosis is only one section of the life cycle of a cell. . Interphase is the main part of the cell cycle. This is where DNA is replicated (a copy is made) to prepare for mitosis.. Overview. 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.. 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.. 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. The features of mitosis that result in the production of genetically identical daughter cells. . The Cell Cycle. Cytokinesis. Mitosis. S. (DNA synthesis). G. 1. G. 2. Figure 9.1 – Chromosomes during cell division. 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.. . 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 _____________ _____________ is a series of steps that cells go through to ____________ and ___________. It can be split into three distinctive processes: ________________, mitosis and ___________________. The first process can be broken down into three distinctive sub-phases. During ____________ and ____________ the cell is carrying on normal cell functions like growing and producing proteins. However, during _____________ the cell’s _____________ is replicated. The cell cycle has _______________ along the way to make sure cells are not reproducing incorrect versions of themselves. In rare occurrences damaged or abnormal cells can get copied which can lead to ______________ or ________________. . 7/22/2009 Cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes. As you grow from an infant to an adult, you pass Advanced Higher Biology. Miss Aitken. The Cell Cycle. Mitosis is the process of cell division.. Some cells are able to reproduce and make copies of themselves by following this sequence of events. The cell cycle consists of 2 phases: interphase (not dividing) and mitosis (dividing). Chromatin. - unwound DNA (loose). . Copied. Sister chromatids. - two identical copies of DNA (loose). . Coiled and Connected. Chromosomes. - two coiled, identical copies of DNA connected to each other (tight). Structure: pancreatic acinar cells. Identification: nucleus, nucleolus, heterochromatin. Heterochromatin. Nucleus. Nucleolus. Pancreas . 158. Pancreas . 158. 32409. Nuclei with . nucleoli. 32409.
