Cell Cycle

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 phases) and the mitotic phase (M phase).

Front

What occurs during the M phase of the cell cycle?

Back

During the M phase, mitosis and cytokinesis occur, resulting in the division of the cell into two daughter cells.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time preparing for division. It includes G1 (cell growth), S (DNA replication), and G2 (preparation for mitosis).

Front

Define cell differentiation.

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, allowing for the formation of different tissues and organs.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that eliminates damaged or unnecessary cells, maintaining healthy tissue.

Front

What is the role of DNA replication in the cell cycle?

Back

DNA replication is crucial for ensuring that each daughter cell receives an identical set of chromosomes during cell division.

Front

What happens during the G1 phase of interphase?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

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

Back

The S phase is significant because it is when DNA is replicated, ensuring that each daughter cell has the same genetic information.

Front

What is the G2 phase?

Back

The G2 phase is the final stage of interphase where the cell prepares for mitosis by producing proteins and organelles needed for cell division.

Front

What are chromatids?

Back

Chromatids are the two identical halves of a duplicated chromosome, which are joined together at a region called the centromere.
