Mitosis and Meiosis

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, involving stages such as prophase, metaphase, anaphase, and telophase.

Front

What is Meiosis?

Back

Meiosis is a specialized form of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes, and includes two rounds of division: Meiosis I and Meiosis II.

Front

What happens during Prophase in Mitosis?

Back

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

Front

What is the significance of Metaphase in Mitosis?

Back

In Metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

What occurs during Anaphase in Mitosis?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring that each new cell will have the correct number of chromosomes.

Front

What is Telophase in Mitosis?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases, during which the cell grows and DNA is replicated.

Front

What is the role of Tetrads in Meiosis?

Back

Tetrads are formed during Prophase I of Meiosis when homologous chromosomes pair up, allowing for crossing over and genetic recombination.

Front

What is Crossing Over?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I of Meiosis, increasing genetic diversity.

Front

What happens during Metaphase I of Meiosis?

Back

During Metaphase I, homologous chromosome pairs align at the equatorial plane of the cell, preparing for separation.
