Cancer

Question 1

What is the common mechanism that causes cancer?

Answer 1

Uncontrolled cell divison

Question 2

What stages in the cell cycle can be targeted to treat cancer

Answer 2

G1 and S phase in interphase

Question 3

G1 Phase

Answer 3

a phase in interphase that produces new organelles and causes the cells to grow in size.

Question 4

S phase

Answer 4

The stage in interphase that causes DNA to replicate.

Question 5

What phase in interphase produces new organelles and causes the cells to grow in size?

Answer 5

G1

Question 6

What phase of the cell cycle are the G1 and S phase found in?

Answer 6

Interphase

Question 7

Mutation

Answer 7

A change in the structure of a gene due to alteration of single base units in DNA resulting in variation

Question 8

Chemotherapy drugs such as vincristine and colchicines disrupt mitosis by binding to tubulin (the subunit of microtubules) and interfering with microtubule assembly and disassembly.

Exactly what mitotic structure do these drugs target, and what effect would that have on cell division?

A-A* (AO3/4)

Answer 8

The drug binds the tubulin, which leads to an error in the chromosome seperation. This could lead to apoptosis

Question 9

Which stages of the cell cycle are common targets for anti-cancer drugs?

Answer 9

S and G1 phase
