7 BrainPOP! Watch the video silently After the video is finished, we will answer the practice questions in our groups The group with the most correct answers will get +5 dojo points or a treat

8

9 Example Write Chromosomes Condense underneath your do-now (or on a separate paper you will staple to your do-now)

10

11 Example Chromosomes are long, continuous threads of DNA Your body has 46 chromosomes in each cell, which are found in pairs During mitosis, DNA tightly wraps around proteins (condenses).

12 Example Why do we only have 46 chromosomes? Do chromosomes ever fail to condense? Fill-in-the-blank: A chromosome is made up of DNA that has numerous along it.

20 Planner: Finish study guide Read 5.3 (weebly) Table of Contents #4 10. Video Notes: Mitosis 11. Power Notes Study Guide 5.2

21 HS-LS 1-4 Standard Students can use a model to illustrate the role of cellular division and differentiation in producing and maintaining complex organisms FLT I will be able to describe the pathway of chromosomes through mitosis & cytokinesis by completing Power Notes 5.2

22 Video Notes We will watch a video on the DETAILS of mitosis Write 8 facts from the video

23

24 Do-Now: Discuss What is the cell cycle? What are the four stages? What happens in the gap phases? When is DNA replicated? Which stage is the longest?

25 Notes Protocol Take notes at Noise Level 0 Raise your hand to question/comment Be prepared to pair-share

26 5.2: Mitosis + Cytokinesis Key idea: Cells divide during mitosis and cytokinesis

27 Recall Recall: Interphase includes G 1, S, and G 2 The cells grows, carries out normal activities, and duplicates DNA

28

29 Chromosome structure DNA double helix DNA and histones Chromatin Supercoiled DNA

30

31 Chromosome Structure 1. DNA is normally loose and stringy

32 Chromosome Structure 2. Chromatin = Strands of DNA loosely wrapped around proteins called histones

33 Chromosome Structure 3. Chromosomes = tightly packed chromatin (Xshaped)

34

35 Squeeze these notes in: 4. Chromatid = One half of a duplicated chromosome (there are two sisters) Centromeres hold sister chromatids together Telomeres protect DNA at the ends of a chromosome chromatid telomere centromere telomere Condensed, duplicated chromosome

36 Pair-Share-Respond 1. What is DNA like normally? 2. What does DNA wrap around to become organized? 3. What is chromatin? 4. What is a chromosome?

37 5.2 Mitosis + Cytokinesis Mitosis and cytokinesis produce two genetically identical daughter cells Interphase prepares the cell to divide During interphase, the DNA is duplicated (S) Parent cell centrioles spindle fibers centrosome nucleus with DNA

38 Add this to the side The purpose of mitosis is to duplicate cells Occurs in body cells (somatic cells) A skin cell undergoing mitosis will produce an identical skin cell A blood cell undergoing mitosis will produce an identical blood cell Etc

39 Interphase Most of the time, the cell is in 1. interphase Interphase is NOT part of mitosis Interphase includes G 1, S, + G 2, but not M phase

40 Mitosis: PMAT Mitosis divides the cell s nucleus in four phases 2. prophase = chromosomes condense & spindle fibers form

41 Mitosis Mitosis divides the cell s nucleus in four phases 3. Metaphase = spindle fibers attach & pull chromosomes to the middle

42 Mitosis Mitosis divides the cell s nucleus in four phases 4. Anaphase = chromatids are pulled apart to opposite sides

43 Mitosis Mitosis divides the cell s nucleus in four phases 5. Telophase = new nuclei form

44 Cytokinesis 6. Cytokinesis = division of cytoplasm

45 Plant vs. Animal Cells (bottom) Animal cells = membrane is cleaved Plant cells = because of the cell wall, a cell plate forms between to separate the cells

46 Pair-Share-Respond 1. In what kind of cells does mitosis occur? 2. What are the steps of mitosis? 3. What must happen at the end of mitosis? 4. Explain how cytokinesis differs in plant and animal cells.

47 CW Work on 5.2 reinforcement/study guide Binder assignments! Review for quiz

48 Quiz/Test Procedure 1. Clear your desk of everything except a pencil 2. Noise level 0 3. Keep eyes on your own quiz/test at all times 4. Raise your hand to ask a question 5. Flip your quiz over and put your head down when you re finished

49 Biology Day 41 Thursday, November 20 Friday, November 21, 2014

50 Brainstorm 11/20-11/21 1. Write the FLT 2. What was your last test score? 3. Did you retake it? Why or why not? 4. List two strategies to help prepare/study for a test or retake. 5. How many class weeks are left in semester 1?

53 Planner: Finish ALL work!! Enjoy your break Table of Contents #4 13. Brainstorm 11/20-11/ Mitosis Review Packet

54 Brainstorm Protocol 1. The goal is to generate the longest possible list as a group 2. When prompted to do so, identify who will provide the first answer 3. Then, go clockwise to the next person. 4. Do not skip people and do not say an answer for them. 5. Only say ONE answer at a time 6. Quantity over quality 7. Stay on topic 8. Pencils must be down when I say time is up 9. Lists must be exactly the same

55 Brainstorm Protocol 1. Go clockwise in order 2. Do not skip people and do not say an answer for them. 3. Only say ONE answer at a time 4. Quantity over quality 5. Stay on topic 6. Pencils must be down when I say time is up 7. Lists must be exactly the same

56 Brainstorm Protocol Identify the person in your group with the longest pinky nail This person will be starting Number your paper underneath your do-now

57 Brainstorm Protocol You will have one minute and thirty seconds to generate answers The winning group will get +5 dojo points each or a treat Your topic is.

58 Brainstorm Protocol What are activities EVERYONE in your group will be doing over break? 1:30 1:29 1:28 1:27 1:26 1:25 1:24 1:23 1:22 1:21 1:20 1:19 1:18 1:17 1:16 1:15 1:14 1:13 1:12 1:11 1:10 1:09 1:08 1:07 1:06 1:05 1:04 1:03 1:02 1:01 1:00 0:59 0:58 0:57 0:56 0:55 0:54 0:53 0:52 0:51 0:50 0:49 0:48 0:47 0:46 0:45 0:44 0:43 0:42 0:41 0:40 0:39 0:38 0:37 0:36 0:35 0:34 0:33 0:32 0:31 0:30 0:29 0:28 0:27 0:26 0:25 0:24 0:23 0:22 0:21 0:20 0:19 0:18 0:17 0:16 0:15 0:14 0:13 0:12 0:11 0:10 0:09 0:08 0:07 0:06 0:05 0:04 0:03 0:02 0:01 End
