PPT-Cell Cycle, Mitosis, Meiosis

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. 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. . Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:. Differentiate between the process of mitosis and meiosis. Demonstrate the movement of chromosomes throughout meiosis. Analyze how meiosis leads to genetic variation. Edited By: Ashlee Palermo. Objectives. Define mitosis.. Define meiosis.. Analyze function of mitosis and meiosis in cell differentiation.. Mitosis:. If a cell wants to make a . ____________. . of itself, it first must copy its DNA (part of a chromosome).. Cells Alive- . http://. cellsalive.com/meiosis.htm. . Meiosis animation. http://. www.youtube.com/watch?v=kVMb4Js99tA. . Meiosis Practice Test. Answer the following questions on the back of your review sheet.. a single . DNA molecule complexed with histone . proteins. DNA is organized within the nucleus as chromosomes. Each chromosome is comprised of subunits called nucleosomes: DNA + proteins. Chromosome numbering/naming. R. r. Source: plant-genetics.kais.kyoto-u.ac.jp. ATGGGCACTGCCACT. A chromosome is a single DNA molecule . complexed . with histone proteins. DNA is highly compacted: DNA + histone proteins = . chromatin. 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.. . 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.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. 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. . 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 Genetic information is passed from one generation to the next on . chromosomes. .. Before cell division, each chromosome is duplicated, or copied.. C. hromosomes. Each chromosome consists of two identical . 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. Unicellular organisms. cell division = reproduction. Multicellular organisms. cell div. needed for development. & for reproduction (meiosis). Mitosis gives each cell. complete set of genetic material.
