Cell cycle and cell division

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, mitosis, and cytokinesis.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2), Mitosis (Prophase, Metaphase, Anaphase, Telophase), and Cytokinesis.

Front

What occurs during interphase?

Back

During interphase, the cell grows, performs its normal functions, and duplicates its DNA in 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 cytokinesis?

Back

Cytokinesis is the final stage of the cell cycle where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What is the role of the nucleus in a cell?

Back

The nucleus stores the cell's DNA and coordinates activities such as growth, metabolism, protein synthesis, and cell division.

Front

How many chromosomes do human somatic cells have?

Back

Human somatic cells have 46 chromosomes, arranged in 23 pairs.

Front

What is the significance of DNA replication?

Back

DNA replication is crucial for ensuring that each daughter cell receives an exact copy of the parent cell's genetic material.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

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 number of chromosomes.
