Mitosis

Front

What is Mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring that each new cell has the same number of chromosomes as the original cell.

Front

What are the main phases of Mitosis?

Back

The main phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

In which phase of Mitosis do the chromosomes align in the center of the cell?

Back

Metaphase.

Front

What happens during Anaphase?

Back

During Anaphase, the sister chromatids are pulled apart to opposite ends of the cell.

Front

What is the role of the centromere in Mitosis?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during Mitosis.

Front

What do the cells look like at the end of Mitosis?

Back

At the end of Mitosis, the two daughter cells are identical to the original cell.

Front

What must be copied before a cell can divide?

Back

DNA must be copied before a cell can divide.

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 occurs during Prophase?

Back

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

Front

What is Telophase?

Back

Telophase is the final phase of Mitosis where the chromosomes begin to de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.
