Cell cycle Mitosis/Meiosis

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 and the mitotic phase.

Front

What are the main stages of the cell cycle?

Back

The main stages 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.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is crossing over?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis, leading to genetic diversity.

Front

What happens during prophase I of meiosis?

Back

During prophase I, homologous chromosomes pair up and crossing over occurs, exchanging genetic material.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for evolution and adaptation, allowing populations to survive changing environments.

Front

What is the S phase of interphase?

Back

The S phase is the part of interphase where DNA replication occurs, resulting in two copies of each chromosome.

Front

What are daughter cells?

Back

Daughter cells are the cells produced as a result of cell division, either through mitosis or meiosis.
