AP LAB 7: CELL DIVISION: MITOSIS AND MEIOSIS How do eukaryotic cells divide to produce genetically identical cells or to produce gametes with half the normal DNA? BACKGROUND One of the characteristics of living things is the ability to replicate and pass on genetic information to the next generation. Cell division in individual bacteria and archaea usually occurs by binary fission. Mitochondria and chloroplasts also replicate by binary fission, which is evidence of the evolutionary relationship between these organelles and prokaryotes. Cell division in eukaryotes is more complex. It requires the cell to manage a complicated process of duplicating the nucleus, other organelles, and multiple chromosomes. This process, called the cell cycle, is divided

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
