Summary Introduction
To explain: The process at molecular level as the chromosomes becomes shorter and thicker during cell division.
Concept introduction: Cell division is a natural process in which a parent cell divides into two daughter cells. In cell nucleus, DNA is present as chromosomes.

WHAT IF? As a cell begins the process of dividing, itschromosomes become shorter, thicker, and individuallyvisible in an LM (light micrograph). Explain what is happening at the molecular level.
Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake.
Draw a 2n=4 cell at G1 of interphase.
Draw the same cell at the start of prophase.
Draw the same cell at metaphase.
Draw the cell(s) that result at the end of cytokinesis.

In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.

Genomes A, B, and C all have basic chromosomenumbers (x) of nine. These genomes were derivedoriginally from plant species that had diverged from each other sufficiently far back in the evolutionarypast that the chromosomes from one genome can nolonger pair with the chromosomes from any other genome. For plants with the following kinds of euploidchromosome complements, (i) state the number ofchromosomes in the organism; (ii) provide terms thatdescribe the individual’s genetic makeup as accurately as possible; (iii) state whether or not it is likelythat this plant will be fertile, and if so, give the number of chromosomes (n) in the gametes.a.

- Classifiation of Llfe A new organism was discovered in a deep sea vent at the bottom of the ocean. The researchers collected the sample and made careful observations of it. The picture at right shows a microscopic image captured at 1000X its actual size. Below are some other observations made: • When DNA was isolated from the cell, it was mixed with an equal portion of histone proteins • There are no visible organelles present inside the cell • The specimen seem to die in the presence of oxygen • Able to live in conditions that mimic deep sea vents without any external food source provided Based on these observations, determine each of the following and provide a clear rationale.

- Solid Wire Models of Cell Division 1- Get four solid wires, 2 long (1 green and 1 red) and two short (1 green and 1 red). This will represent the chromatin in a cell. The wires of the same length are homologous. Red wires will represent the chromatin from the female parent while green wires represent the chromatin from the male parent. Label the chromatin as follows: long green- 1a short green- 2c long red- 1b short red- 2d 2- Let the cell pass S phase. Replicate or duplicate each chromatin fiber. Do this by getting another set of wire identical to the original set. Label as before. 3- Combine the replicated chromatin fiber using masking tape. The tape will also mark the position of the centromere. For the short chromatin, place the tape exactly at the middle while for the long chromatin, place it at a point % from the end of the wire. 4- Assume that the chromosome fibers are folded.
