THE CELL CYCLE-Chapter 12 ? Ability to reproduce = one characteristic of living things ? Continuity of life based on the reproduction of cells ? Cell division functions in reproduction, growth, and repair? UNICELLULAR ORGANISMS use cell division for reproduction? MULTICELLULAR ORGANISMS use cell division to:? -repair/renew cells that die from normal wear and tear? -grow and develop from a single fertilized egg (zygote)? -reproduce asexually (EX: plants grow by cuttings) ? Results in genetically identical daughter cells ? DNA molecules packaged into chromosomes ? GENOME= cell?s genetic information Prokaryotes genome - single circular loop of DNA Eukaryotes - several DNA molecules in multiple chromosome bundles

Mica Piro Chapter 12: The Cell Cycle Most Cell Division Results in Genetically Identical Daughter Cells (12.1) Cellular Organization of the Genetic Material A cell?s endowment of DNA, its genetic information, is called its genome A prokaryotic genome is often a single DNA molecule Eukaryotic genomes usually consist of a number of DNA molecules All of this DNA has to be copied, or replicated, before the cell can divide to form genetically identical daughter cells, and then the 2 copies must be separated so that each daughter cell ends up with a complete genome The replication and distribution of so much DNA is manageable because the DNA molecules are packaged into structures called chromosomes, because they take up certain dyes used in microscopy

Campbell's Biology, 9e (Reece et al.) Chapter 12 The Cell Cycle In this chapter, 24 questions are new, and 12 have been altered to incorporate new material from the textbook. As in the other chapters, any questions that depend on figures or introductory scenarios have been placed at the end of the chapter rather than in concept sequence. Multiple-Choice Questions 1) The centromere is a region in which A) chromatids remain attached to one another until anaphase. B) metaphase chromosomes become aligned at the metaphase plate. C) chromosomes are grouped during telophase. D) the nucleus is located prior to mitosis. E) new spindle microtubules form at either end. Answer: A Topic: Concept 12.1 Skill: Knowledge/Comprehension

Chapter 12 The Cell Cycle Overview: The Key Roles of Cell Division Rudolf Virchow ? said ?where a cell exists, there must have been a preexisting cell, just as the animal arises only from an animal and the plant only from a plant?. Summarized by saying: ?omnis cellula e cellula? ? means every cell comes from a cell. Cell division ? plays several important roles in the life of an organism: Unicellular organism ? i.e. amoeba ? cell divides and forms duplicate, complete organisms. Larger scale ? cell vision can produce progeny (descendents) Enables sexually reproducing organisms to develop form a single cell (zygote) Can function in renwal or repair ? replacing cells that die (i.e. bone marrow, skin)
