Question

“Draw a circle inside the plate to resemble the nuclear membrane.
2 – Place four sets of DNA into the nuclear membrane of
the cell. Draw on a sheet of paper what this model
step looks like using colored pencils. Label it
“Interphase.”
3 – Erase the nuclear membrane on the plate. Cross each
piece of DNA, within each set, to make a
chromosome. Draw two dots on each end of the cell
to represent the centrioles. Draw on your sheet of
paper what this model step looks like using colored
pencils. Label it “Prophase.”
4 – Line the chromosomes at the middle of the cell. Draw
spindle fibers as strings that connect to each center of
the chromosome or centromere. Draw on your sheet
of paper what this model step looks like using colored
pencils. Label it “Metaphase.”
5 – Pull the chromosomes apart to separate them on
each side of the cell. Erase the spindle fibers and
centrioles. Draw on your sheet of paper what this
model step looks like using colored pencils. Label it
“Anaphase.”
6 – Draw a circle around each set of chromosomes. Draw
a line to separate the cells. Draw on your sheet of
paper what this model step looks like using colored
pencils. Label it “Telophase.”
Write a paragraph easy worded 3-4 sentences explaining how your model represents mitosis.“

State what the model is trying to convey in 2 easy worded sentences

Answer 1

This model shows the main steps of mitosis by changing the way the DNA and cell parts look on the plate. In Interphase the DNA is loose inside the nuclear membrane. In Prophase the nuclear membrane disappears and the DNA becomes visible as chromosomes with centrioles nearby. Then in Metaphase the chromosomes line up, in Anaphase they are pulled apart, and in Telophase two new nuclei form so the cell becomes two identical daughter cells.

The model is trying to show how one cell divides into two cells. It also shows that the chromosomes are copied and then separated so each new cell gets the same DNA.
