Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What must be copied before a cell can divide?

Back

DNA must be copied before a cell can divide.

Front

What happens to the nucleus during prophase?

Back

During prophase, the nucleus dissolves, allowing the chromosomes to become visible.

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 structure made of DNA and proteins that contains genetic information; it consists of two sister chromatids joined at a centromere.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in organisms, ensuring that cells divide accurately.

Front

What are the stages of mitosis?

Back

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

Front

What happens during anaphase?

Back

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