#13

What is the role of spindle fibers during mitosis?

To move chromosomes to opposite poles of the cell

To replicate DNA

To divide the cytoplasm

#14

Which of the following accurately describes the difference between mitosis and meiosis?

Mitosis produces diploid cells, while meiosis produces haploid cells

Mitosis involves one round of division, while meiosis involves two rounds of division

Mitosis results in genetically identical daughter cells, while meiosis results in genetically diverse daughter cells

Mitosis occurs only in somatic cells, while meiosis occurs only in gametes

#15

What is the significance of crossing over during meiosis?

It increases genetic variation among offspring

It prevents DNA replication errors

It ensures accurate segregation of chromosomes

It promotes cell growth

#16

During which phase of the cell cycle does the cell commit to undergoing division?

G1 phase

S phase

G2 phase

M phase

#17

What is the significance of independent assortment during meiosis?

It ensures that sister chromatids are separated during cell division

It increases genetic variation by randomly distributing homologous chromosomes

It promotes accurate segregation of chromosomes into daughter cells

It regulates the timing of the cell cycle
