1 JOPRY! Unit 4 xam Review ame Tuesday, ecember 5 th,

2 ow to play JOPRY! The class will be split into two teams, the R team and the RN team. When a question is displayed, the R team will use the keys on their clickers to answer. The RN team will use the keys to answer. The team with the IST PRNT of correct responses will earn the points for that question, N the right to pick the next category! Let's do a practice question to make sure everybody understands how to play. o on to the Practice Question 2

5 1 Insert Question ere ycles and Stuff 100 pts The cell cycle includes 4 major phases. Which of the following lists them in the correct order? 1, S, 2, M 1, 2, S, M 1, S, M, 2 1, M, 2, S / : 1, S, 2, M ack 5

6 2 Insert Question ere ycles and Stuff 200 pts Which of the following events takes place during the " 1 " phase of the cell cycle? the cell divides the cell increases in size the chromosomes condense the cell prepares for cell division / : the cell increases in size ack 6

7 3 Insert Question ere ycles and Stuff 300 pts cell has 24 chromosomes during the " 1 " phase of interphase. fter this cell goes through the process of MIOSIS, there are four daughter cells. ach of these daughter cells has 6 chromosomes 12 chromosomes 24 chromosomes 48 chromosomes / : 12 chromosomes ack 7

8 4 Insert Question ere ycles and Stuff 400 pts uring the "S" phase of the cell cycle, the genetic material of a cell is copied through a process called synthesis. cytokinesis. N replication. histone formation. / : N replication. ack 8

9 5 Insert Question ere ycle and Stuff 500 pts Which of these graph shapes most accurately depicts the changes that occur to the amount of N within a cell during two rounds of the cell cycle? / : ack 9

10 1 Insert Question ere Multiplying by ividing 100 pts The process of mitosis includes 4 major phases. Which of the following lists them in the correct order? anaphase, metaphase, prophase, telophase telophase, prophase, metaphase, anaphase prophase, metaphase, anaphase, telophase metaphase, prophase, telophase, anaphase / : prophase, metaphase, anaphase, telophase ack 10

11 2 Insert Question ere Multiplying by ividing 200 pts Which of the following observations can be made when an animal cell is in metaphase? The chromosomes are aligned along the center of the cell. Two identical nuclei are forming on opposite sides of the cell. The cell membrane is pinching off to form two daughter cells. The sister chromatids have separated and become daughter chromosomes. / : The chromosomes are aligned along the center of the cell. ack 11

12 3 Insert Question ere Multiplying by ividing 300 pts What would be the most likely result of cell division if cytokinesis came before mitosis? oth daughter cells would die immediately. oth daughter cells would survive indefinitely. One daughter cell would have two nuclei and the other would have no nucleus. our daughter cells would be produced, each with half the number of chromosomes as the parent cell. / : One daughter cell would have two nuclei and the other would have no nucleus. ack 12

13 4 Insert Question ere Multiplying by ividing 400 pts uring which phase of mitosis do the "sister chromatids" become "daughter chromosomes?" anaphase prophase telophase metaphase / : anaphase ack 13

14 Multiplying by ividing 500 pts 5 Insert Question ere Imagine a hypothetical cell that has 24 chromosomes during the " 1" phase of interphase. fter this cell goes through the process of MITOSIS, there are two daughter cells. ach of these daughter cells has 6 chromosomes 12 chromosomes 24 chromosomes 48 chromosomes / : 24 chromosomes ack 14

15 1 Insert Question ere MisLLaneous 100 pts umans are diploid and have 46 chromosomes. ow many chromosomes are found in each human gamete? / : 23 (one set haploid) ack 15

16 MisLLaneous 200 pts 2 Insert Question ere is the process by which haploid gametes form a diploid zygote. Mitosis Meiosis ertilization ifferentiation / : ertilization ack 16

17 3 Insert Question ere MisLLaneous 300 pts Some drugs are effective at stopping the development of cancer because they bind to and disrupt the function of the spindle apparatus during cell division. Such drugs most likely affect which molecules? the proteins that make up microtubules the polymerase enzymes that make copies of N the histone proteins that the N wraps around to form a condensed chromosome the kinetochore proteins through which the spindle fibers attach to the centromere of each chromosome / : the proteins that make up microtubules. ack 17

18 4 Insert Question ere MisLLaneous 400 pts The two main stages of the M phase of the cell cycle are called mitosis and cytokinesis prophase and metaphase metaphase and telophase N synthesis and preparation for cell division / : mitosis and cytokinesis ack 18

19 5 Insert Question ere MisLLaneous 500 pts Which of the following statements correctly describes sister chromatids and homologous chromosomes? omologous chromosomes and sister chromatids are two phrases describing the same thing. omologous chromosomes are exactly the same, sister chromatids are similar but not identical. Sister chromatids are exactly the same, homologous chromosomes are similar but not identical. omologous chromosomes are inherited from the same parent, sister chromatids come from different parents. / : Sister chromatids are exactly the same, homologous chromosomes are similar but not identical. ack 19
