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.
You can draw this out on paper

N.B: Which substance is responsible for the bonding of chromatids and centromeres. Don't Answer like this:Due to continuous dehydration nuclear chromatin condenses to form visible thread like structure, known as chromosome.

- 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. This will now represent the chromosomes. OR Varrow_forwardcell type: 9) Label the figure below.
