Cell cycle , Mitosis and Meiosis

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of interphase (G1, S, G2) and the mitotic phase (M).

Front

What happens during interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis. It includes G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

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 unique daughter cells, each with half the number of chromosomes of the original cell.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is crucial because it is when DNA replication occurs, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What are the main stages of mitosis?

Back

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

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell is divided into two daughter cells.

Front

How many cells are produced at the end of meiosis?

Back

At the end of meiosis, four cells are produced, and they are genetically unique from each other.

Front

What is the difference between mitosis and meiosis?

Back

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

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms in the cell cycle that ensure the proper division of the cell and prevent errors such as DNA damage.
