Mitosis and Meiosis Review

Front

What is Mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring equal distribution of genetic material.

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.

Front

Define 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 the two sister chromatids are joined together.

Front

What occurs during Prophase?

Back

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

Front

What happens in Metaphase?

Back

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

Front

Describe Anaphase.

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms, and the chromosomes begin to de-condense.

Front

What is the significance of Mitosis?

Back

Mitosis is essential for growth, development, and tissue repair in multicellular organisms.
