POP FLASHCARD- The Cell Cycle & Cancer

Front

What is the S phase in the cell cycle?

Back

The S phase (Synthesis phase) is the part of the cell cycle where DNA is replicated, ensuring there is enough DNA for the daughter cells during cell division.

Front

What is cytokinesis?

Back

Cytokinesis is the process during cell division where the cytoplasm of a parental cell divides into two daughter cells, completing the cell division process.

Front

How many daughter cells are produced from one round of mitosis?

Back

Mitosis produces 2 daughter cells that are genetically identical to the original cell.

Front

What is a tumor?

Back

A tumor is an abnormal mass of tissue that forms when cells divide uncontrollably, often associated with cancer.

Front

What are benign tumors?

Back

Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body, making them easier to remove.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory pathways in the cell cycle that ensure the cell is ready to proceed to the next phase, preventing errors such as DNA damage.

Front

What is the difference between malignant and benign tumors?

Back

Malignant tumors are cancerous and can invade nearby tissues and spread to other parts of the body, while benign tumors are non-cancerous and do not spread.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is the first gap phase where the cell grows and prepares for DNA replication, ensuring it has the necessary resources.

Front

What happens during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis, checking for DNA damage and ensuring all DNA is replicated.

Front

What is apoptosis and its role in cancer prevention?

Back

Apoptosis is programmed cell death that helps eliminate damaged or unnecessary cells, playing a crucial role in preventing cancer.
