Mitosis

Front

What is mitosis?

Back

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

Front

What happens during prophase?

Back

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

Front

What is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes line up along the center of the cell and spindle fibers attach to each chromosome at the centromere.

Front

What occurs during anaphase?

Back

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

Front

What is telophase?

Back

Telophase is the final stage of mitosis where the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid at the centromere.

Front

Define the cell cycle.

Back

The cell cycle is the sequence of stages that a cell goes through in order to grow and divide, including interphase and mitotic phase.

Front

What is interphase?

Back

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

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is a chromosome?

Back

A chromosome is a structure made of DNA and protein that contains genetic information; humans typically have 46 chromosomes.
