MITOSE

Mitosis is a type of what kind of cellular process?

• Cellular respiration

• Cellular division

• Cellular mutation

• Cellular fusion

What is the primary role of mitosis in multicellular organisms?

• To decrease the number of cells

• To promote growth and tissue regeneration

• To produce genetically diverse cells

• To eliminate old cells without replacement

During interphase, which of the following processes occur?

• Cell division

• Protein synthesis and DNA replication

• Chromosome separation

• Cell death

What is the first stage of mitosis called, and what is its significance?

• Metaphase, it is the shortest stage.

• Anaphase, it is when chromosomes separate.

• Prophase, it is the longest stage.

• Telophase, it is when the cell divides completely.

What characterizes the metaphase stage of mitosis?

• Chromosomes condense and become visible.

• Chromosomes migrate to the equatorial region of the cell.

• Chromosomes are pulled apart to opposite poles.

• The nuclear envelope re-forms around chromosomes.

During metaphase, what structure do chromatids attach to?

• Centriole

• Kinetochore

• Nucleus

• Ribosome

At what stage do chromosomes reach their highest level of compaction?

• Prophase

• Anaphase

• Metaphase

• Telophase

During anaphase, what happens to the sister chromatids?

• They are duplicated

• They are separated

• They are condensed

• They are synthesized

What role do microtubules play during anaphase?

• They duplicate the chromosomes

• They condense the chromatids

• They shorten and pull chromatids to opposite poles

• They synthesize new DNA

What is the main function of mitosis?

• To produce energy

• To divide the cell into two identical cells

• To create genetic diversity

• To repair damaged DNA
