What are sister chromatids?
Duplicated chromosomes attached at the centromere (center)
uncoiled/uncondensed DNA
division of cytoplasm
one division to create 2 identical cells
What is cytokinesis?
duplicated chromosomes attached at the centromere
uncoiled/uncondensed DNA
keeps sister chromatids together
division of cytoplasm
What happens during the G1 phase of the cell cycle?
DNA is replicated
cell divides
cell rests
cell grows and prepares
What is the function of spindle fibers?
Replicates DNA
Helps separate chromosomes evenly for the daughter cells
Increases the growth of the cell
Divides the cytoplasm
What happens during the S phase of the cell cycle?
DNA replicates
Cell divides
Cell rests
Cell grows and prepares
What happens during cell division?
mitosis and cytokinesis
preparation for mitosis
DNA replication
help separate chromosomes evenly for daughter cells
During mitosis, how is genetic material put into each daughter cell?
The chromosomes split evenly between daughter cells
The chromosomes are duplicated before cell division
The chromosomes stay in the original cell
The chromosomes are randomly distributed
The total number of chromosomes in a human cell is 46. How many chromosomes will be in each cell after mitosis?
23
46
92
Varies
What is the correct order of the cell cycle?
G2, G1, M, S

S, G1, G2, M
G1, M, G2, S
What prevents normal cells from dividing?
growth factors
tissue damage
contact inhibition when cells touch each other
cyclins
Which of the following is FALSE about stem cells?
They could be used to repair spinal cord injuries
They can develop into many different cell types
They can be found in bone marrow, liver and skin cells
They have all genes being expressed or "turned on"
What is true about cyclins?
signal the cell to stop the cell cycle if DNA mutations are present
is an inhibitory protein causing the cycle to stop
is a stimulating protein causing the cycle to proceed
if not functional, can lead to cancer cells dividing uncontrollably
What is FALSE about differentiated cells?
they have the same DNA in their cells compared to other types of cells
parts of the DNA sequence is used in each type of cell
they originated from stem cells
the entire DNA sequence is used in each type of cell
What does the G1 checkpoint check for?
DNA damage
chromosome spindle attachement
if DNA is replicated correctly
if cells divide correctly
Which of the statements best describes the diagram?
All daughter cells have different DNA and different functions due to certain genes being turned on and off
All daughter cells have the same DNA and the same functions due to certain genes being turned on and off
All daughter cells have the same DNA, but different functions due to certain genes being turned on and off
All daughter cells have different DNA and the same functions due to certain genes being turned on and off
