UNDERSTANDING CELLULAR DIVISIONS:MITOSIS 1. Read the contents on pages 31, 32 and 33. 2. Colour the black and with sketch on page 65. 3. Make the activities on page number 33. 4. Follow these instructions: ** Draw a cell with four Molecules of DNA. Two come from the father and the other two, come from the mother. Draw one big molecule and the another one smaller. Use red colour for Father molecules and blue colour for mother molecules. Each molecule will represent a Chromosome. ** Draw the cell in Interphase before S period. (BS) ** Draw the cell in Interphase after S period.(AFS) 4. Imagine that this cell suffers the Mitosis: ** Draw the cell in Prophase condensing the Chromosomes. What Happens inside the Cytoplasm? Draw the Spindle.( Previous PRO) ** Draw the Cell in Prophase a little time before Metaphase.(Late PRO) ** Draw the cell in Metaphase.(MET) ** Draw the Cell in Anaphase.(ANA) ** Draw the DAUGTHER CELLS during Telophase.(TELO) 5.

UNDERSTANDING CELLULAR DIVISIONS:MITOSIS

1. Read the contents on pages 31, 32 and 33.2. Colour the black and with sketch on page 65.3. Make the activities on page number 33.4. Follow these instructions: ** Draw a cell with four Molecules of DNA. Two come from the father and the

other two, come from the mother. Draw one big molecule and the another one smaller. Use red colour for Father molecules and blue colour for mother molecules.

Each molecule will represent a Chromosome. ** Draw the cell in Interphase before S period. (BS) ** Draw the cell in Interphase after S period.(AFS)4. Imagine that this cell suffers the Mitosis: ** Draw the cell in Prophase condensing the Chromosomes. What Happens

inside the Cytoplasm? Draw the Spindle.( Previous PRO) ** Draw the Cell in Prophase a little time before Metaphase.(Late PRO) ** Draw the cell in Metaphase.(MET) ** Draw the Cell in Anaphase.(ANA) ** Draw the DAUGTHER CELLS during Telophase.(TELO)5. Fill out the following chart.
