The Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, resulting in the formation of new daughter cells.

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

During Interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

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 happens during Prophase?

Back

During Prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite poles of the cell during mitosis.

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 a cleavage furrow?

Back

A cleavage furrow is an indentation that forms in the cell membrane during cytokinesis in animal cells, leading to cell division.

Front

What is the significance of the G1 phase in the cell cycle?

Back

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