Cell cycle and cell division

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and the mitotic phase (M).

Front

What are the main phases of the cell cycle?

Back

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

Front

What happens during G1 phase?

Back

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

Front

What occurs during the S phase?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the G2 phase?

Back

The G2 phase is the final stage of interphase where the cell prepares for mitosis, including the synthesis of proteins and organelles.

Front

What is mitosis?

Back

Mitosis is the process of nuclear division in which a single cell divides to produce two identical daughter cells.

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 process that follows mitosis, where the cytoplasm divides, resulting in two separate cells.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle, preventing errors such as DNA damage.

Front

What is the first checkpoint in the cell cycle?

Back

The first checkpoint occurs between the G1 and S phases, assessing whether the cell is ready for DNA synthesis.
