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.

Answer 1

This model shows the stages of mitosis by using the plate and drawings to stand for a cell and its parts. Interphase has loose DNA inside the nuclear membrane, and erasing the membrane in prophase shows it breaking down while the DNA coils into visible chromosomes and centrioles appear. In metaphase the chromosomes are lined up in the middle and spindle fibers attach, and in anaphase the fibers pull the chromosome halves to opposite sides. In telophase two new nuclei form around each set of chromosomes and the drawn line and circles show the cell splitting into two identical daughter cells.
