Cell Cycle and Mitosis REVIEW

Front

What are oncogenes?

Back

Oncogenes are mutated forms of genes that can transform a normal cell into a tumor cell, leading to unregulated cell division.

Front

What is the role of oncogenes in tumor formation?

Back

The presence of an oncogene leads to unregulated cell division, which can result in the formation of tumors.

Front

What are the stages of the cell cycle?

Back

The stages of the cell cycle include interphase, prophase, metaphase, anaphase, telophase, and cytokinesis.

Front

During which phases of the cell cycle does the cell grow?

Back

The cell grows during the G1 and G2 phases of the cell cycle.

Front

What is the S phase responsible for?

Back

The S phase is responsible for DNA replication.

Front

How does cell division contribute to growth in multicellular organisms?

Back

Cell division allows for the production of new cells, which is essential for growth in multicellular organisms.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including growth and DNA replication.

Front

What happens during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, preparing for separation.

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.
