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

• 1

• 2

• 3

• 4

Which of the following is NOT true about mitosis and meiosis?

• Mitosis occurs in somatic cells, while meiosis occurs in germ cells.

• Mitosis produces daughter cells with half the number of chromosomes, while meiosis maintains the chromosome number.

• Mitosis involves one cell division, while meiosis involves two.

• Mitosis produces genetically identical cells, while meiosis produces cells that are different from the parent and each other.

What is the significance of crossing over in meiosis?

• It decreases genetic variation.

• It ensures that daughter cells are identical.

• It increases genetic variation among gametes.

• It repairs damaged DNA.

During which stage of meiosis are sister chromatids separated?

• Anaphase I

• Anaphase II

• Telophase I

• Telophase II

Which of the following statements about mitosis and meiosis is FALSE?

• Mitosis results in two daughter cells, while meiosis results in four.

• Mitosis can occur in both haploid and diploid cells, while meiosis only occurs in diploid cells.

• Both mitosis and meiosis include a phase called metaphase.

• Meiosis results in daughter cells that are genetically identical to the parent cell.

What is the role of mitotic spindles during mitosis?

• They duplicate the DNA.

• They break down the nuclear membrane.

• They assist in the separation of chromosomes.

• They synthesize RNA.
