MITOSIS AND MEIOSIS QUIZ-ZOO 100

What is the primary purpose of mitosis in multicellular organisms?

• To create genetic variation

• To produce identical daughter cells for growth and repair

• To reduce chromosome number by half

• To produce gametes

Which phase of mitosis involves the alignment of chromosomes along the cell's equator?

• Prophase

• Metaphase

• Anaphase

• Telophase

During which phase do sister chromatids separate and move to opposite poles?

• Prophase

• Metaphase

• Anaphase

• Telophase

Which structure is responsible for organizing and separating chromosomes during mitosis?

• Nucleus

• Spindle fibers

• Centrioles only

• Ribosomes

What happens to the nuclear membrane during prophase?

• It breaks down

• It becomes thicker

• It duplicates

• It moves to the center of the cell

How many daughter cells are produced at the end of mitosis?

• One

• Two

• Four

• Eight

If a cell’s spindle fibers are disrupted, which stage of mitosis would be most affected?

• Prophase

• Metaphase

• Anaphase

• Telophase

A scientist observes a cell under a microscope with chromosomes lined up in the center. Which stage of mitosis is the cell in?

• Prophase

• Metaphase

• Anaphase

• Telophase

In a certain mutation, cells cannot enter anaphase correctly. What might be a likely outcome of this mutation?

• Cells fail to form a spindle

• Cells have duplicated chromosomes that do not separate

• Cells immediately complete cytokinesis

• Cells have twice as many centrioles

How would a malfunctioning cytokinesis process affect the end result of mitosis?

• The cell might end up with one cell having two nuclei

• The cell would produce more DNA

• The daughter cells would be identical

• The nuclear membrane would not dissolve
