cell cycle

Cells that rarely divide will spend most of their time in what particular phase of the cell cycle?

• Go

• G1

• G2

• S

This check point of the cycle dictates whether the cell will continuously divide or stop, and it also checks the cell size, presence of growth factors and damage of the DNA.

• G₁ checkpoint

• G₂ checkpoint

• S checkpoint

• M checkpoint

In this phase, the cell is preparing for the cell division in the mitotic stage.

• Go

• G1

• G2

• S

DNA replication occurs in what phase of cell cycle?

• Interphase

• Growth phase

• Mitotic phase

• Synthesis Phase

Which checkpoint ensures sister chromatids are positioned to be split correctly?

• G₁ checkpoint

• G₂ checkpoint

• S checkpoint

• M checkpoint

In this phase, the cell is preparing for the cell division of the mitotic phase.

• Go

• G1

• G2

• S

If the M checkpoint is not cleared, what specific stage of mitosis will be blocked?

• Anaphase

• Metaphase

• Prophase

• Telophase

Programmed cell death is known as ____________.

• Apoptosis

• Oncogene

• Proto-oncogene

• Tumor suppressor gene

How many cell cycle checkpoints are there?

• 1

• 2

• 3

• 4

The correct sequence of mitosis:

• metaphase, anaphase, telophase, prophase

• prophase, metaphase, anaphase, telophase

• prophase, anaphase, metaphase, telophase

• telophase, metaphase, prophase, anaphase
