5.A - Cell Cycle and Mitosis

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 and mitotic phase.

Front

What are the main stages of Mitosis?

Back

The main stages of Mitosis are prophase, metaphase, anaphase, and telophase.

Front

Define Prophase.

Back

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

Define Metaphase.

Back

Metaphase is the second stage of mitosis where chromosomes align at the cell's equatorial plane.

Front

Define Anaphase.

Back

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

Front

Define Telophase.

Back

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

Front

What is a Centriole?

Back

A centriole is a cylindrical structure involved in cell division, helping to organize the mitotic spindle.

Front

What is a Chromatid?

Back

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

Front

What is a Chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What happens during Interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis.
