Cell Cycle and Mitosis

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (which includes G1, S, and G2 phases) and the Mitotic phase (which includes Mitosis and Cytokinesis).

Front

What occurs during the G1 phase of Interphase?

Back

During the G1 phase, the cell grows and carries out normal functions while preparing for DNA replication.

Front

What is the S phase of Interphase responsible for?

Back

The S phase is responsible for DNA replication, where the cell duplicates its genetic material.

Front

What happens during the G2 phase of Interphase?

Back

During the G2 phase, the cell prepares for cell division by producing proteins and organelles needed for mitosis.

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 are the stages of Mitosis?

Back

The stages of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What is Cytokinesis?

Back

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

Front

How long does a cell spend in Interphase compared to Mitosis?

Back

A cell spends the majority of its life in Interphase, which can last for hours to days, while Mitosis takes only a short time, usually less than an hour.

Front

What is the significance of the cell cycle checkpoints?

Back

Cell cycle checkpoints are critical control mechanisms that ensure the cell is ready to proceed to the next phase, preventing errors in cell division.

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the progression of the cell cycle by activating cyclin-dependent kinases (CDKs).
