Cell Division: Mitosis & Meiosis

Cell Molecular Stories Booklet: Chapter #1

GOAL: students will create a booklet (chapter #1) which explains the two types of cell division: MitosisMeiosis. After downnloading the scrambled pictures and text, students will first separate and sequence the pictures for Mitosis vs Meiosis and then match the text descriptions (letted) to the appropriate pictures. This booklet could be created in a variety of ways: use word processing (e.g., MS Word) or slide show software (e.g., MS PowerPoint), or design an interactive web page.

PROJECT DIRECTIONS:

1) Download thescrambled pictures and text from the Weeblywebpage: geneticsraypec.weebly.com

  • I recommend using Copy-N-Paste to more easily work with the pictures and text on your own computer

2) Arrange the pictures of Mitosis (7) and Meiosis (13) in the CORRECT SEQUENCE

  • Most pictures should be used only once…a few may be used twice or more as needed
  • Use 7 total pictures for the Mitosis story …(InterPMATC & 2 final daughter cells)
  • Use 13 total pictures for the Meiosis story….. (InterPMATC InterPMATC & final egg or 4 sperm produced)
  • Study the color-coded clues carefully !!! (homologous chromosomes are the same general color  dark green - light green, dark blue - light blue, dark purple – light purple)
  • Pay close attention to the haploid (n) vs diploid (2n) markings

3) Match each of the 7 picturesof Mitosis(InterPMATC & 2 daughter cells) with the appropriate text from the List of 28 possible Cell Cycle Activities / Descriptions

  • For computers with MS WORD, open the WORD file and copy / paste the scrambled TEXT as needed
  • Otherwise, retype text as needed from the class handout “List of 28 possible cell cycle A/ D”
  • HINT: you should use 12 activities / descriptions from “The List” for Mitosis (I4, P3, M1, A1, T2, C1)
  • CAUTION: some activities / descriptions on “The List” are NOT used to narrate Mitosis

4) Match each of the 13 picturesof Meiosis (InterPMATC InterPMATCfinal egg or sperm produced) with the appropriate text from the List of 28 possible Cell Cycle Activities / Descriptions

  • For computers with MS WORD, open the WORD file and copy / paste the scrambled TEXT as needed
  • Otherwise, retype text as needed from the class handout “List of 28 possible cell cycle A/ D”
  • HINT: you should use 23 activities / descriptions from “The List” for Meiosis (I3, P5, M1, A1, T2, C1, I21, P23, M21, A21, T22, C21)
  • HINT: you might have to use some activities / descriptions for the second or third time
  • CAUTION: some activities / descriptions on “The List” are NOT used to narrate Meiosis

5) LABEL (and draw an arrow to ID) the following 10items at least once in your cell division booklet…..also use circles and brackets as needed to help clearly ID each of the 10 concepts below:

  • Centromere, equator line, nucleolus, “single” chromosome, “double” chromosome, tetrad, chromatin, chiasma, evidence of crossing-over, homologous chromosomes

6) Turn in your booklet (with the SELF-GRADED SCORING GUIDE) by the due date=

  • Bring a PRINTED copy of your booklet chapter 1 to class

OR

  • UPLOAD your file to the Weebly link: geneticsraypec.weebly.com
  • Plan B = send Mr. Roberts an email () and SHARE your MM Booklet file that is stored on your Google Drive

List of 28 “possible” Cell cycle Activities / Descriptions

Directions: As you develop your MM Booklet, match each cell cycle picture to the appropriate activities / descriptions from the list of 28 possible choices below. HINT: If your booklet is correct, you should use (copy-n-paste) 12 activities /descriptions in your Mitosis story and 23 activities /descriptions in your Meiosis story. This means that you can use some activities/descriptions two or three times, but be careful…..some activities/descriptions on the list are NOT used.

A Homologous chromosomes separate and move toward opposite poles of the cell as the spindle begins to collapse

B The cell membrane pinches in and separates the cytoplasm into two diploid daughter cells

C The cell membrane pinches in and separates the cytoplasm into two haploid daughter cells

D The cell membrane pinches in and separates the cytoplasm into four diploid daughter cells

E The cell membrane pinches in and separates the cytoplasm into four haploid daughter cells

F The nucleoli and nuclear membrane disintegrate and disappear from view

G The spindle disintegrates and disappears from view as the nucleoli reform and nuclear membranes reform around diploid sets of DNA

H The spindle disintegrates and disappears from view as the nucleoli reform and nuclear membranes reform around haploid sets of DNA

I Several chiasmata may form as homologous non-sister chromatids cross-over and trade genetic codes

J the DNA blueprint is replicated as all the genetic codes are copied

K the cell spends up to 90% of the cell cycle time and the nucleoli are visible in the nucleus

L the DNA supercoils and condenses into a visible set of diploid “double” chromosomes

M the DNA supercoils and condenses into a visible set of haploid “double” chromosomes

N the DNA supercoils and condenses into a visible set of diploid “single” chromosomes

O the DNA supercoils and condenses into a visible set of haploid “single” chromosomes

P 2 centrioles spread apart as a “football-shaped” microtubule spindle begins to form

Q The homologous “double” chromosomes attach by their centromeres to the spindle fibers and form a single file line up and down the equator of the cell

R The homologous “single” chromosomes attach by their centromeres to the spindle fibers and form a single file line up and down the equator of the cell

S The homologous “double” chromosomes attach by their centromeres to the spindle fibers and move close together as they form a tetrad of 4 side-by-side sister chromatids

T A haploid set of “double” chromosomes attach by their centromeres to the spindle fibers and form a single file line up and down the equator of the cell

U The cell grows larger in size as new proteins and cell organelles are produced

V A haploid set of “double” chromosomes attach by their centromeres to the spindle fibers and move close together as they form a tetrad of 4 side-by-side sister chromatids

W A haploid set of “single” chromosomes attach by their centromeres to the spindle fibers and form a single file line up and down the equator of the cell

X The sister chromatids split and are pulled toward opposite poles of the cell as the spindle begins to collapse

Y “single” chromosomes uncoil and uncondense and return to chromatin

Z “double” chromosomes uncoil and uncondense and return to chromatin

AA the DNA looks like “thin strands of spaghetti” which are known as chromatin

BB Pairs of homologous chromosome tetrads are aligned up and down the equator of the cell
