Transcript cell cycle and cancer 2016x

Tuesday – 10/25
• On your warm-up sheet of paper from
yesterday, complete the following:
Describe the various stages of the life cycle of a
human being from beginning to end.
Cell Cycle vs. Life Cycle
The cell cycle is similar to the life cycle of a
human in that they both have various phases
that are associated with distinct characteristics.
Cell Cycle Video
• As you watch the video clip below, try and list
the phases of cell growth and division that
are mentioned in the video.
• Record your answer below your warm-up.

Cell Cycle Notes
Using your diagram, fill out the blanks to the
best of your ability using the word bank.
Fill in the blank
• The purpose of mitosis is for growth and division of cells
• As a cells get bigger, in interphase (G1) it,
– Uses up more oxygen and glucose more quickly
– Places more demand on its DNA
– Has more trouble transporting enough material across its
membrane
• The cell then replicates its DNA (S phase) which mean it
makes an identical copy or synthesis of DNA
• The next phase G2 is preparation for mitosis, which
means copying of organelles and growing even more to
prepare for mitosis
• Cell division consists of 2 parts
– Mitosis – 4 phases that divides the nucleus
– Cytokinesis – the division of cytoplasm and the cell
membrane
Mitosis Hands
• Lets learn mitosis hands.
• On the back of your warm-up, number 1-6 on
the left-hand side of your paper.
• Leave some room between each number.
• Write the name of each phase and the
defining characteristics of each phase.
– Be sure to focus on the genetic material.
Spinner!
Line up your Circle Cut Out
with the Full page notes
side with the pictures.
Carefully use your brad to
poke a hole through both
pages to create your
spinner!
Wednesday: 10/26
• Use your spinner notes that you made yesterday
to answer the following:
1. Which phase of the cycle is the
longest? What 3 events make up
this phase?
2. List the order of events of the cell
cycle, starting with G1.
3. What is the purpose of mitosis?
Let’s Practice!
• For each picture, write the following things on
your notebook paper.
• Use your spinner to help you!
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
3. Draw a picture
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
3. Draw a picture

2. Lined up in the middle
1. The phase the cell is in.
2. The defining

phase.
3. Draw a picture

2. The defining
characteristic of that
phase.
3. Draw a picture

2. Daughter cells are
pulling apart from
each other, but not
completely
separated.
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
3. Draw a picture
1. Prophase
2. Chromosomes are
formed (looks like
worms)

2. The defining
characteristic of that
phase.
3. Draw a picture
1. Anaphase
2. Chromosomes are
pulling away.
(Opposite sides of
the cell)
Take a minute to look over your notes
about the phases of the cell cycle
below. Memorize them. Be able to
label this. You will be questioned on
this…
On a notebook sheet of paper, put the pictures
in order (draw your own pictures) and write the
name/description of each phase
Check our Answers!!!
Below are plant cells in various stages of the cell cycle.
On a sheet of paper, number 1-18. Describe what phase the cell is in,
and write a brief description of what is occurring in this phase. Start
with the numbers that have lightening bolts, and then complete as
many as you can. You have 5 minutes to finish as much as you can.
Complete the questions with a star by them.

Cancer Reading
• As you read through the passage, underline or
highlight the key info using the dry erase
marker.
• Then, using the info in the passage, fill out the
graphic organizer to the best of your ability.
Cancer Notes
• Write any additional notes on the back of your
graphic organizer over the next 2 slides.
Disruptions
• Disruptions in mitosis can lead to diseases such as cancer.
• Cells contain internal and external regulators. Internal regulators
allow the cell cycle to proceed only when certain processes have
occurred (ex. all chromosomes have been replicated)
• Cancer is an uncontrolled synthesis of cells. If a mutation occurs in
the genes that control the cell cycle, then mitosis could occur
before the cell has gone through the all stages of interphase or
even if the cell has been damaged.
• Example: The p53 gene product normally senses DNA damage and
either halts the cell cycle until it can be repaired or, if the damage
is too massive; triggers apoptosis. Apoptosis is programmed cell
death.
