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

In the eukaryotic cell, it is the longest stage of the cell cycle and generally its function is to prepare the cell to division process.

• Interphase

• Mitotic phase

• Synthesis Phase

• All of the above

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

What is not the prerequisite for clearance at the G2 checkpoint?

• 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
