Total questions: 52
Worksheet time: 38mins
Where does Mitosis take place?
where growth and repair are happening
in your hair cells only
in your blood cells only
During prophase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
DNA condenses into chromosomes, centrioles and spindle fibers appear
2 new identical cells are created
DNA gets copied
During telophase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
centrioles and spindle fibers appear
Each DNA gets pull to the opposite sides of the cell
2 new nuclei form
During cytokinesis
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
Cell membrane pinches to make 2 new identical daughter cells
Each DNA gets pull to the opposite sides of the cell
2 new nuclei form
In general, the purpose of a checkpoint in the cell cycle is:
To allow the cell to rest
To check for any errors
To signal cell replication
To signal DNA replication
DNA replication occurs during:
Anaphase
Interphase
Metaphase
Prophase

6 chromosomes each
12 chromosomes each
24 chromosomes each
48 chromosomes each

What is a difference between a cell in the G1 phase and a cell in the G2 phase of the cell cycle?
A cell in the G2 phase would be smaller than a cell in the G1 phase.
A cell in the G2 phase would have more mitochondria than a cell in the G1 phase
A cell in the G1 phase would have more DNA in its chromosomes than a cell in the G2 phase.
DNA replication occurs in the G1 phase but not in the G2 phase.

germ cells
egg and sperm cells
What occurs during the S-phase of the cell cycle & when does it occur?
The DNA is copied. It occurs during interphase - BEFORE mitosis begins.
The DNA is copied. It occurs during mitosis as the nucleus divides.
The nucleus divides. It occurs during mitosis.
The cytoplasm divides. It occurs after mitosis.
Which of the following is NOT a somatic cell?
skin cell
sperm cell
muscle cell
nerve cell
Which of the following is the stage of mitosis in which the spindle fiber is splitting the chromosomes and moving them to opposite ends of the cell?
Prophase
Metaphase
Anaphase
Telophase
Why are chromosomes duplicated (copied) during the S-phase of interphase before mitosis?
to ensure that when cells divide, each daughter cell has a complete set
so that the daughter cells will be genetically different from the parent cell
chromosomes are not duplicated during interphase, they are copied during mitosis
there is no such thing as a chromosome
