Cell Cycle and Cancer

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation to its division into two daughter cells. It includes interphase (G1, S, G2) and the mitotic phase (M).

Front

What are the main phases of mitosis?

Back

The main phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What occurs during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis. It consists of G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is the significance of the G1 phase?

Back

The G1 phase is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, the cell replicates its DNA, resulting in two identical sets of chromosomes.

Front

What is the role of the G2 phase?

Back

The G2 phase is the final stage of interphase where the cell continues to grow and prepares for mitosis by producing necessary proteins and organelles.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is the key event in anaphase?

Back

In anaphase, sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.
