Let?s begin with a review of several terms that you may already know. Define: gene: A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses) locus: A specific place along the length of a chromosome where a given gene is located gamete: A haploid reproductive cell, such as an egg or sperm. Gametes unite during sexual reproduction to produce a diploid zygote. male gamete: Sperm female gamete: Eggs

Chapter 12 The Cell Cycle: Practice Quiz Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. Self-Quiz Questions ____ 1. Increases in the enzymatic activity of some protein kinases important for the regulation of the cell cycle are due to a. kinase synthesis by ribosomes. b. activation of inactive kinases by binding to cyclins. c. conversion of inactive cyclins to active kinases by means of phosphorylation. d. cleavage of the inactive kinase molecules by cytoplasmic proteases. e. a decline in external growth factors to a concentration below the inhibitory threshold.

Campbell's Biology, 9e (Reece et al.) Chapter 13 Meiosis and Sexual Life Cycles New questions are mostly at higher skill levels in this chapter. The new questions represent newer material both in the chapter and in the area of biological research. All questions with accompanying art work or questions grouped together as sets have been organized at the end of the chapter. Multiple-Choice Questions 1) If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants? A) Backtrack through her previous experiments to obtain another plant with the same traits.

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

Lecture Outline for Campbell/Reece Biology, 7th Edition, ? Pearson Education, Inc. 12-1 Chapter 12 The Cell Cycle Lecture Outline Overview: The Key Roles of Cell Division ? The ability of organisms to reproduce their kind is the one characteristic that best distinguishes living things from nonliving matter. ? The continuity of life is based on the reproduction of cells, or cell division. Cell division functions in reproduction, growth, and repair. ? The division of a unicellular organism reproduces an entire organism, increasing the population. ? Cell division on a larger scale can produce progeny for some multicellular organisms. ? This includes organisms that can grow by cuttings.

Cytosis

Endocytosis and Exocytosis Endocytosis is when a material is taken through the membrane by folding inwards or basically it is moving things that are outside of the cell, into the cell by extending the membrane outwards and surrounding the food particle. (General Term) Exocytosis is the reverse of endocytosis. It is the discharge of the materials from the vesicles inside the cell, to the outside of the cell. Then the vesicle joins the cell membrane. There are three types of endocytosis: Pinocytosis ? the process of taking in something that is liquid. Phagocytosis ? the process of taking something that is rather solid like fragment of an organic sell. Receptor mediated endocytosis ? Taking in specific molecules such as Low Density Lipoproteins (LDL) Receptor Mediated endocytosis
