Mitosis quiz

What is the primary outcome of mitosis?

• Production of genetically diverse cells

• Formation of gametes

• Creation of two identical daughter cells

• Reduction in chromosome number

Which of the following processes primarily occurs during interphase of the cell cycle?

• Cell division

• DNA duplication and cell growth

• Nuclear envelope breakdown

• Chromatid separation

What happens to the nuclear envelope during the early stages of mitosis?

• It remains intact throughout the process.

• It fragments and disappears.

• It expands to accommodate new chromosomes.

• It forms a cleavage furrow.

What is the primary role of the centrosome during mitosis?

• To synthesize new DNA.

• To organize microtubules and form the spindle.

• To regulate cell growth.

• To form the cell membrane.

• Yes

• No

What are the two identical halves of a duplicated chromosome called?

• Homologous chromosomes

• Sister chromatids

• Centromeres

• Kinetochores

Which two major events occur during Interphase?

• Chromosomes condense and mitotic spindle forms.

• Nuclear envelope fragments and microtubules attach to kinetochores.

• DNA is copied and centrosomes replicate.

• Chromatids separate and cell elongates.

What happens to the nuclear envelope and microtubules during Prometaphase?

• The nuclear envelope reforms and microtubules disappear.

• The nuclear envelope fragments and microtubules attach to kinetochores.

• The nuclear envelope remains intact and microtubules shorten.

• The nuclear envelope expands and microtubules detach from kinetochores.

What is the primary event that occurs during Anaphase?

• Chromosomes align at the metaphase plate.

• The nuclear envelope reforms.

• Sister chromatids separate and move to opposite poles.

• The cell elongates and a cleavage furrow forms.
