Mitosis

Front

What can result from DNA damage that affects cell-signaling pathways?

Back

Tumors

Front

Why is it important to repair DNA damage before mitosis?

Back

To ensure each daughter cell is healthy and can continue growth.

Front

What are oncogenes?

Back

Mutated forms of genes that can transform a cell into a tumor cell.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors are non-cancerous and do not spread, while malignant tumors are cancerous and can invade other tissues.

Front

During which phase of the cell cycle do chromosomes line up in the middle of the cell?

Back

Metaphase

Front

What is the role of cell signaling pathways in the cell cycle?

Back

They regulate the progression of the cell cycle and ensure proper cell division.

Front

What happens if cell division is unregulated?

Back

It can lead to the formation of tumors.

Front

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

Back

It is the phase where the cell grows and prepares for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication takes place.
