Cellular Division and Reproduction Quiz

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

DNA replication takes place during the Interphase stage of the cell cycle.

A normal somatic cell in humans has 46 chromosomes.

Sexual reproduction involves the fusion of gametes (sperm and egg cells) from two parents.

The primary function of gametes is to fuse during fertilization, forming zygotes with a complete set of chromosomes.

Metaphase in mitosis is characterized by the alignment of chromosomes along the cell's equatorial plane.

Centrioles play a crucial role in separating chromosomes during cell division.

Meiosis is the process that produces gametes (sperm and egg cells) with genetic diversity.

Spindle fibers help in the separation of sister chromatids during mitosis.

Interphase is not a stage of mitosis; it is a phase in the cell cycle before mitosis.

Cyclins regulate the cell cycle by activating checkpoints that ensure the proper progression of the cell through its phases.

Cytokinesis, the division of the cytoplasm, occurs during Telophase of the cell cycle.

Asexual reproduction results in offspring that are genetically identical to the single parent.

Homologous chromosomes exchange genetic material during Prophase I of meiosis through the process of crossing over.

Crossing over increases genetic variation by exchanging segments between homologous chromosomes during meiosis.

Yeast reproduces exclusively through mitosis, a form of asexual reproduction.

Homologous chromosomes separate during Anaphase II of meiosis.

Non-disjunction is the term for the failure of chromosomes to separate properly during meiosis, leading to abnormal chromosome numbers in daughter cells.
