Mitosis and Meiosis

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 is Meiosis?

Back

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

Front

What is a chromosome?

Back

A chromosome is a structure made of DNA and protein that contains genetic information. It consists of two identical sister chromatids connected at the centromere.

Front

What is a chromatid?

Back

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

Front

What is the centromere?

Back

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

Front

What happens during Prophase 1 of Meiosis?

Back

During Prophase 1, homologous chromosomes pair up and exchange genetic material through a process called crossing over.

Front

What happens during Metaphase 1 of Meiosis?

Back

During Metaphase 1, homologous chromosome pairs line up along the center of the cell.

Front

What happens during Anaphase 1 of Meiosis?

Back

During Anaphase 1, the homologous chromosomes are pulled apart to opposite ends of the cell.

Front

What happens during Telophase 1 of Meiosis?

Back

During Telophase 1, the cell divides into two new cells, each with half the number of chromosomes.

Front

What happens during Metaphase 2 of Meiosis?

Back

During Metaphase 2, individual chromosomes line up along the center of the cell.
