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 and the mitotic phase.

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 (Mitosis and Cytokinesis).

Front

What occurs during interphase?

Back

Interphase is the phase where 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 mitosis?

Back

Mitosis is the process of nuclear division in eukaryotic cells, resulting in two identical daughter nuclei.

Front

What happens during prophase?

Back

During prophase, chromosomes condense and become visible, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What occurs during telophase?

Back

During telophase, chromosomes unwind back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is cytokinesis?

Back

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

Front

What is the longest phase of the cell cycle?

Back

Interphase is the longest phase of the cell cycle, where the cell spends most of its time preparing for division.

Front

What is the significance of the G1 phase?

Back

The G1 phase is crucial for cell growth and preparation for DNA replication.
