Exploring Mitosis and Meiosis Concepts

What is the primary function of mitosis in eukaryotic cells?

• To ensure each daughter cell receives identical genetic material.

• To eliminate damaged cells from the organism.

• To reduce the chromosome number by half.

• To increase genetic diversity through recombination.

Which type of cell division results in daughter cells with half the number of chromosomes of the parent cell?

• Mitosis

• Binary fission

• Meiosis

• Duplication

What is the main reason prokaryotic cells do not undergo mitosis?

• They lack a nucleus.

• They do not have cellular organelles.

• They only have one chromosome.

• They replicate their DNA too quickly.

How do eukaryotic cells compact their DNA to fit within the nucleus?

• Through binary fission

• By wrapping DNA around histone proteins

• By forming circular DNA structures

• By randomly tangling the DNA strands

What does the G1 phase of the cell cycle primarily involve?

• DNA replication

• Cytokinesis

• Chromosome separation

• Cell growth and preparation for DNA replication

What is the role of checkpoints in the cell cycle?

• To initiate cytokinesis

• To condense the chromosomes

• To ensure the cell is ready to proceed to the next phase

• To replicate DNA

During which phase are the sister chromatids separated into daughter cells?

• Telophase

• Metaphase

• Anaphase

• Prophase

What is the primary purpose of meiosis in sexual reproduction?

• To generate unique genetic combinations in offspring

• To create identical cells for tissue repair

• To maintain the same genetic information across generations

• To produce cells for asexual reproduction

During which phase of meiosis does crossing over occur?

• Telophase I

• Anaphase I

• Prophase I

• Metaphase I

What is the result of independent assortment in meiosis?

• All gametes receive identical genetic information

• Chromosomes are duplicated

• Chromatids are separated into new cells

• Gametes receive a mix of chromosomes from both parents
