PPT-Mitosis and Cytokinesis Chapter 5.2

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.

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. Efficiency . Smaller the cell = quicker it can work. Transport of Substances. Cellular communication. Ratio of surface area to volume. Other reasons for cellular division. Growth. Replace damaged cells.

HINT: What should a normal karyotype look like? . 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 ________________. . 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).
