Cell Growth

Cells spend the majority of their lives in

• Interphase

• Mitosis

• Synthesis 

• Gap 2

The cell cycle is regulated by this

• cyclins

• stem cells

• cyclin-dependent kinases

• both cyclins and cyclin-dependent kinases

When cells go through mitosis repeatedly without entering interphase, this results

• arthritis

• cancer

• mutation

• diabetes

What can cause cells to become cancerous?

• Genetic factors

• Exposure to toxins

• Excessive exposure to UV light

• All of the above

What is the role of cyclin and Cdk in the cell cycle?

• They allow cells to move forward in the cycle

• They initiate apoptosis

• They replicate DNA

• They regulate cell growth

What is the role of the cell cycle checkpoints?

• To check if the cell is growing well enough

• To check if the DNA is damaged

• To check if the cell has the resources it needs

• All of the above

What happens if a cell doesn't meet the requirements of a checkpoint?

• It pauses until the issue is fixed

• It continues to the next phase of the cell cycle

• It undergoes apoptosis

• It replicates its DNA incorrectly

What stage of Mitosis is being represented in the image?

• Prophase

• Metaphase

• Anaphase

• Telophase

Which stage of the cell cycle is represented by letter ¨B¨

• ________G1phase- Cell does majority of its growing in this phase. Cell increases in size and makes new proteins and organelles.

• ________S Phase-chromosomes are replicated and the synthesis of DNA molecules takes place.

• ________G2 phase-preparation for mitosis. Many organelles and molecules needed for cell division are produced.

• ________M phase- Process of Cell Division
