MITOSIS
By now you should have a basic understanding of the cell cycle. As
we watch the video over the cell cycle and mitosis you should
take notes over what you still don’t understand. Remember, you
are building your knowledge of this subject, in order to be able to
do well on your DLT quiz this week.

MITOSIS
1. Now we will model the cell cycle and process of mitosis with two
paper plates and pipe cleaners. What will the paper plates
represent? What will the pipe cleaners represent?
2. What is the first phase of the cell cycle? What three phases occur
within this phase? What happens in each of these phases?
3. What is the first phase of cell division (M phase)?
4. What is the second phase of cell division?
5. What is the third phase of cell division?
6. What is the fourth phase of cell division?
7. What is the last step of cell division?
8. What four phases make up mitosis?

DLT 1 Knowledge Check…let’s see what you know so far.
You will need one blank sheet of paper, you do not have to remove it
from your binder. In fact, I would keep it in your binder, so that
you can use it to study after we grade it. You will also need
something to write with.
There are three parts to this check, so you will need to number your
paper as follows:
Part A: 1 – 14.
Part B: A – E.
1-10.
Part C: 1 – 18.
Now, let’s begin.
Cell Cycle Quiz
______First and longest phase of mitosis;
chromatin coils into visible chromosomes
______Shortest phase of mitosis; chromosomes
move to the equator; chromatids are attached
by centromeres
______Centromeres split and chromatid pairs
are pulled apart
______Final phase of mitosis; nuclear
membrane begins to reappear; new cells
prepare for their new independent existence
______Busiest phase of the cell cycle; includes
growth and DNA replication
______Division of the nuclear material; two new
daughter cells formed that are identical to the
mother
______Division of the cytoplasm
______Tangled mass of DNA and proteins; state
of DNA during interphase
______Cell structures composed of microtubule
fibers; “pull” apart sister chromatids
______Identical halves of a duplicated parent
chromosome; held together by a centromere
______Midline of a cell during division
A. ANAPHASE
B. CENTRIOLE
C. CENTROMERE
D. CHROMATID
E. CHROMATIN
F. CHROMOSOME
G. CYTOKINESIS
H. EQUATOR
I. INTERPHASE
J. METAPHASE
K. MITOSIS
______Structure that contains DNA; appears
right before cellular division and vanishes
following cell division
L. PROPHASE
______Structures found in animal cells that
duplicate during interphase and move to
opposite poles during prophase
N. TELOPHAS
______Cell structure that joins two sister
chromatids of a chromosome
M. SPINDLE

I CAN DESCRIBE THE BASIC PROCESS OF MEIOSIS.
Now we are going to begin learning about the process of meiosis. By
now you should have a good understanding of the cell cycle and
mitosis. As we watch the video over meiosis you should take
notes over any new concepts. Remember, you are building your
knowledge of this new DLT, in order to be able to do well on your
DLT quiz this week.
I CAN DESCRIBE THE BASIC PROCESS OF MEIOSIS.
Exit Slip:
1. What occurs during metaphase 1 of meiosis?
a. Centromeres of replicated chromosomes line up along the
cell’s equator.
b. Centromeres divide as sister chromatids move toward opposite
poles of the cell.
c. Homologous chromosome pairs line up along the cell’s
equator.
d. Homologous chromosomes move toward opposite poles of the
cell.
