Cell cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes for each daughter cell.

Front

What is mitosis?

Back

Mitosis is the process of nuclear division in which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

Cytokinesis is the division of the cytoplasm, resulting in two separate daughter cells after mitosis.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate sister chromatids and pull them to opposite poles of the cell during anaphase.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is the uncontrolled growth and division of cells due to mutations that disrupt the normal regulation of the cell cycle.

Front

What occurs during prophase?

Back

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

Front

What occurs 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 occurs during anaphase?

Back

During anaphase, sister chromatids are pulled apart and move toward opposite poles of the cell.
