Mitosis, Cell Cycle and Cancer

Front

What are oncogenes?

Back

Oncogenes are mutated forms of genes that can transform a normal cell into a tumor cell.

Front

What is the role of oncogenes in tumor formation?

Back

Oncogenes lead to unregulated cell division, which can result in tumor formation.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells.

Front

What is one function that is NOT performed by mitosis?

Back

Passing on DNA to offspring is not a function of mitosis.

Front

When does DNA replication occur in the cell cycle?

Back

DNA replication occurs before a cell divides to ensure each daughter cell receives a complete set of DNA.

Front

What holds sister chromatids together?

Back

Sister chromatids are held together by the centromere.

Front

What is apoptosis?

Back

Apoptosis is programmed cell death, a process that eliminates damaged or unnecessary cells.

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are interphase (G1, S, G2) and mitotic phase (M).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two copies of each chromosome.
