Mitosis: When Cells Divide

Mitosis: When Cells Divide

The Cell Cycle:

• a series of events cells go through

• Interphase: G_1, S, G₂

• Mitosis: Prophase, Metaphase, Anaphase, Telophase/Cytokinesis

Multiple Choice

Which of the following is in the correct order?

• G₁, S_, G₂, M

• M, G₁,S, G₂

• G₁, G₂, S. M

Interphase

• is the longest stage of the cell cycle

• it has three parts

• 
  

Multiple Choice

Which of the following is the longest?

• Interphase

• Mitosis

The three stages of interphase include:

• G₁= Cells grow and make proteins

• S= Chromosomes replicate or copy

• G₂= Cells grow a little more

Multiple Choice

During which phase do the chromosomes replicate?

• G₁

• S

• G₂

• Mitosis

During the S phase:

• The Chromatin condenses

• Chromosomes are formed

• The homologous pairs form sister chromatids

• The sister chromatids are exact copies of each other and are connected at the centromere

Multiple Choice

Which of these is in the correct order?

• Chromosomes, Sister Chromatids, Chromatin

• Chromatin, Chromosomes, Sister Chromatids

Multiple Choice

Where are the sister chromatids attached?

• Centrioles

• Centromere

• Waist

Mitosis:

• is when a cell divides the genetic material of the nucles

• it is the shortest part of the cell cycel

• it has four stages

• 
  

Multiple Choice

How many stages of mitosis are there?

• 1

• 2

• 3

• 4

The Stages of Mitosis:

• Prophase

• Anaphase

• Metaphase

• Telophase/Cytokinesis

Prophase

• Nucleus disappears

• Centrioles replicate

• Sister chromatids are clearly visible

• 
  

Metaphase

• Sister Chromatids line up in the middle of the cell

• Spindle fibers formed by the centrioles are attached to the centromere of each sister chromatid

• 
  

Anaphase:

• The sister chromatids pull apart as the spindle fibers shorten

• A cleavage furrow indicates the beginning of two separate cells

Multiple Choice

Which is in the proper order?

• prophase, metaphase, anaphase, telophase

• telophase, prophase, anaphase, metaphase

• metaphase, telophase, interphase, prophase

Telophase:

• A nucleus forms in each new cell

• The chromosomes form chromatin

Cytokinesis

• occurs along with Telophase

• the contents of the cytoplasm are divided between the two cells

• two identical daughter cells have been formed!

Multiple Choice

What is the first stage of mitosis called?

• anaphase

• metaphase

• telophase

• prophase

Multiple Choice

During which stage of mitosis do the chromosomes line-up in the middle of the cell?

• anaphase

• prophase

• metaphase

• telophase

Multiple Choice

The nucleus disappears during:

• prophase

• metaphase

• telophase

• anaphase

Multiple Choice

When does the "Cytoplasm" divide?

• Mitosis

• Cytokinesis

Multiple Select

At the end of mitosis you have:

• two daughter cells

• identical cells

• four daughter cells

• replicated chromosomes

• cells in interphase
