The 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) and the mitotic phase (M).

Front

What are the main stages of the Cell Cycle?

Back

The main stages of the Cell Cycle are Interphase (G1, S, G2) and the Mitotic Phase (M).

Front

What happens during Interphase?

Back

During Interphase, the cell grows, duplicates its DNA, and prepares for mitosis. It consists of G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is the purpose of the S phase?

Back

The S phase is where DNA replication occurs, resulting in two identical sets of chromosomes for the daughter cells.

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells after mitosis.

Front

What does the G in G1 and G2 stand for?

Back

The G in G1 and G2 stands for 'gap', indicating periods of growth and preparation between the phases of the cell cycle.

Front

What is the Spindle checkpoint?

Back

The Spindle checkpoint is a control mechanism that ensures all chromosomes are properly attached to the spindle apparatus before proceeding with mitosis.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes arrive at opposite poles, begin to de-condense, and are enclosed by new nuclear membranes.

Front

What is the role of checkpoints in the Cell Cycle?

Back

Checkpoints are regulatory pathways that ensure the cell cycle progresses only when certain conditions are met, preventing errors in cell division.

Front

What is the M phase?

Back

The M phase is the mitotic phase of the cell cycle where cell division occurs, including both mitosis and cytokinesis.
