What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

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, each with half the number of chromosomes of the parent cell.

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 centromere?

Back

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

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome that are connected by a centromere and are formed during DNA replication.

Front

What happens during anaphase of mitosis?

Back

During anaphase of mitosis, sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell receives an identical set of chromosomes.

Front

What happens during anaphase of meiosis?

Back

During anaphase of meiosis, homologous chromosomes are pulled apart to opposite poles, while sister chromatids remain together.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes with half the chromosome number.

Front

How many chromosomes do daughter cells have after mitosis if the parent cell has 60 chromosomes?

Back

Daughter cells will have 60 chromosomes after mitosis.
