Mitosis and Meiosis Review

Front

What is mitosis?

Back

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

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes (sperm or eggs).

Front

What are the main phases of mitosis?

Back

The main phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication, and is not part of mitosis.

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 is a chromatid?

Back

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

Front

What is a centromere?

Back

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

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 occurs during metaphase?

Back

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

Front

What occurs during anaphase?

Back

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