Cell Cycle and Cancer

What is mitosis?

• The process of cell division that results in two daughter cells with identical genetic material.

• A type of cell division that produces four genetically different cells.

• The phase of the cell cycle where DNA is replicated.

• A process that occurs only in prokaryotic cells.

What is the term for scheduled cell death?

• Necrosis

• Apoptosis

• Autophagy

• Cellular senescence

Which of the following is not a factor that can cause a mutation?

• Radiation

• Chemicals

• Viruses

• Temperature

What is the function of the G2 phase?

• Normal cell functions

• DNA replication

• Cell division

• Protein synthesis

What is the cell cycle?

• A process of photosynthesis in plants.

• The series of events that take place in a cell leading to its division and replication.

• A method of cellular respiration.

• The stages of protein synthesis.

What is the role of checkpoints in the cell cycle?

• To ensure that the cell is ready to proceed to the next phase and to prevent errors.

• To speed up the cell division process.

• To promote uncontrolled cell growth.

• To facilitate the exchange of genetic material between cells.

What regulates the cell cycle?

• Proteins

• Carbohydrates

• Lipids

• Nucleic Acids

What is a mutation?

• A change in the DNA sequence that can lead to changes in protein function.

• A process that repairs damaged DNA sequences.

• A type of genetic engineering used to create new species.

• A method of cloning organisms for research purposes.

Where do you find checkpoints in the cell cycle?

• At the beginning of each phase

• After each phase

• Only during DNA replication

• At the end of the cell cycle

What happens during the S phase of the cell cycle?

• DNA replication occurs, resulting in two identical sets of chromosomes.

• Cell growth and preparation for mitosis take place.

• Chromosomes are divided into two daughter cells.

• The cell undergoes metabolic changes to prepare for division.
