PPT-Cell Division – Mitosis and the Cell Cycle

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 . 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. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . When Making New Cells . Goes Terribly . Wrong. Regulating the cell cycle.

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. . Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the 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 172BIOLOGY CELL CYCLE AND CELL DIVISION171 The stages through which a cell passes from one division to the next is calledthe cell cycle. Cell cycle is divided into two phases called (i) Interphase
