Mitosis and Meiosis

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.

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes of the parent cell.

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation until it divides into two daughter cells, including interphase and the mitotic phase.

What happens during Interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis or meiosis.

Front

What is crossing over in Meiosis?

Back

Crossing over is the process during meiosis where homologous chromosomes exchange segments of genetic material, leading to genetic variation.

Front

What are sister chromatids?

Back

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

What occurs during Anaphase of Mitosis?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.

What is Cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

What is the difference between Mitosis and Meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse daughter cells.
