Cancer and check points

Cancer is:

• Cells undergoing normal division

• When cells begin to die

• Uncontrolled cell division

Mutations occur during:

• DNA replication

• Mitosis

• Meiosis

• When cells divide

A mutation is a change in:

• The RNA sequence of an organism

• The DNA sequence of an organism

• The speed of the cell division

• The number of cells that divide

Critical control point where stop and go signals can regulate the cycle

• Cell regulator

• Cell check

• Point of interest

• Check point

What regulates checkpoints?

• Golgi apparatus

• Proteins

• Cells

• Mitochondria

T/F: When cells are in contact with each other, cell division is taking place

• True

• False

What happens if control of the cell cycle is lost?

• DNA replication takes place

• Mitosis takes place

• Nothing, it just reboots itself

• uncontrolled cell division

At what checkpoint does this take place: checks for suitable growth conditions and checks for DNA damage

• M

• G1

• G2

• S

At what check point does this take place? Checks for proper spindle assembly and correct attachment to centromeres 

• M

• G1

• G2

• S

At what check point does this take place? Checks for appropriate cell size required for successful division

• Checks for any replication faults

• M

• G1

• G2

• S
