Cell Cycle and Mitosis Flashcard

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two copies of each chromosome.

Front

What are the phases of the cell cycle?

Back

The cell cycle consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, develops, and prepares for division; it includes G1, S, and G2 phases.

Front

What occurs during the G1 phase?

Back

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

Front

What occurs during the G2 phase?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing the necessary proteins and organelles.

Front

When are chromosomes visible under a microscope?

Back

Chromosomes are visible during cell division, specifically during prophase and metaphase.

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 final step of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.
