Cell Division and Genetics

What is the primary reason cells divide?

• To increase their size

• To replace old or damaged cells

• To stop growing

• To change their function

What limits the size of a cell?

• The amount of DNA available

• Surface area-to-volume ratio

• The type of organelles present

• The cell’s location

What are the two main stages of the cell cycle?

• Interphase and mitosis

• Prophase and metaphase

• G1 and G2

• Meiosis I and Meiosis II

What is the purpose of mitosis?

• To create genetic diversity

• To produce gametes

• To create two identical daughter cells

• To copy DNA without dividing

In which phase of mitosis do chromosomes align in the middle of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

What happens during anaphase?

• Chromosomes condense

• Sister chromatids separate and move to opposite poles

• The nuclear envelope reforms

• Spindle fibers attach to chromosomes

Which structure is responsible for pulling chromosomes apart during mitosis?

• Golgi apparatus

• Lysosome

• Spindle fibers

• Mitochondria

During which phase does cytokinesis typically occur?

• Metaphase

• Anaphase

• Telophase

• Prophase

What is the purpose of meiosis?

• To produce identical cells

• To repair damaged cells

• To create haploid gametes

• To make diploid cells

How many rounds of cell division occur in meiosis?

• One

• Two

• Three

• Four
