Mitosis and Cell Cycle

Front

What is a chromosome?

Back

A chromosome is a structure within cells that contains DNA and genetic information. It is made up of chromatin and is visible during cell division.

Front

List the stages of mitosis in order.

Back

The stages of mitosis in order are: Prophase, Metaphase, Anaphase, Telophase.

Front

What occurs during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell prepares for mitosis by producing proteins and organelles, and by increasing in size.

Front

What is the role of the centromere in cell division?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together. It plays a crucial role in the separation of chromatids during mitosis.

Front

What happens during prophase?

Back

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

Front

What is the significance of metaphase in mitosis?

Back

Metaphase is significant because the chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

Describe anaphase in the context of mitosis.

Back

Anaphase is the stage where the sister chromatids are pulled apart to opposite poles of the cell, ensuring that each new cell will have the same number of chromosomes.

Front

What occurs during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense back into chromatin.

Front

What is the cell cycle?

Back

The cell cycle is the 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 is the function of the mitotic spindle?

Back

The mitotic spindle is a structure made of microtubules that segregates chromosomes into the daughter cells during mitosis.
