A) Lysosome B) Nucleus C) Ribosome D) Golgi Apparatus E) None of the above

8) In which phase of mitosis do the chromosomes condense and become visible?

A) Prophase B) Metaphase C) Anaphase D) Telophase E) Cytokinesis

9) What is happening during G1 of the cell cycle?

A) DNA is replicated B) Normal cell growth and activity C) Stockpiling of enzymes and ATP for mitosis D) the cell divides

10) Daughter cells of mitosis…

A) are genetically unique B) have half the chromosomes of the parent cell C) are clones D) will never divide

11) In which phase of mitosis do the attachments between sister chromatids break and the chromosomes begin to be pulled to opposite ends of the cell?

A) Interphase B) Anaphase C) Prophase D) Telophase E) Metaphase
