Problems can take place at any point in the cell cycle. The longer a cell spends in a given phase, the higher the chance something can go wrong. Given this, which phase is most likely to have the most problems?

Match the phases with their main activities.

Stavka koja se može prevući		Odgovarajuća stavka
G1 Phase		phase in which cells spend most of their life
S phase		includes mitosis and cytokinesis
Interphase		part of interphase in which the DNA replicates
M-Phase		part of interphase in which the cell is growing

How does cancer relate to the cell cycle?

Cancer can be caused by lack of cell division.

Cancer is always hereditary, cell cycle has no effect.

Cancer only affects large cells.

Cancer can be caused by uncontrolled cell division.

Cancer has a relation with S-phase only.

What role do checkpoints play in the cell cycle?

They stop all cell functions.

Checkpoints encourage faster division.

Checkpoints are only in healthy cells.

Checkpoints prevent damaged cells from dividing.

Checkpoints do apoptosis.

What is the role of Checkpoint in M-phase

To check DNA replication

To check if Cell is growing well

To check if cell have everything needed to grow

To check if chromosomes are correctly lined in the middle

To check if the chromosomes belong to same species
