Cell Cycle and Mitosis REVIEW

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

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

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

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

The S phase is responsible for DNA replication.

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

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

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

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

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