8. What is the relationship between binary fission and cell division?
a) Binary fission creates proteins necessary for cell division.
b) Binary fission is the name of cell division in cancer cells.
c) Binary fission is a type of cell division that occurs in prokaryotic cells.
d) Binary fission creates nuclear membranes for the process of cell division.
7. Some scientists are investigating whether daily use of aspirin helps prevent the growth of cancerous tumors. Which of these designs would be the most effective for a clinical trial?
a) Use two groups of participants. Have one group take aspirin daily and one group take nothing.
b) Use two groups of participants. Have one group take aspirin daily and one group take a placebo (an inactive pill) daily.
c) Use one group of participants. Have all members of the group take aspirin daily.
d) Use one group of participants. Have all members of the group alternate between taking aspirin and a placebo (an inactive pill
6. A scientist wants to investigate the causes of skin cancer in humans. Which of the following processes would be the most appropriate to investigate?
a) binary fission
b) replication of plasmid DNA
c) cellular respiration
d) cell transformation
5. What is one difference between the G1 phase and the G2 phase?
a) In the G1 phase, the nuclear membrane breaks down. In the G2 phase, the nuclear membrane reforms.
b) In the G1 phase, chromosomes are separated. In the G2 phase, chromosomes are still together.
c) In the G1 phase, the cell is growing. In the G2 phase, the cell has stopped growing.
d) In the G1 phase, DNA has not been replicated. In the G2 phase, DNA has been replicated.
3. How are chromosomes and plasmids alike?
a) both are linear in shape
b) both appear only in prokaryotic cells
c) both are found in the nucleus
d) both are DNA molecules
4. Which of these processes occurs in both binary fission and mitosis?
a) replication of DNA
b) formation of nuclear envelopes
c) rearrangement of organelles
d) segregation of plasmids
2. What is one difference between how DNA is organized in prokaryotic cells and eukaryotic cells?
a) Eukaryotic cells typically have linear DNA structures, while prokaryotic cells have circular DNA structures.
b) Eukaryotic cells' DNA is packed into structures called plasmids, while prokaryotic cells' DNA is not.
c) Prokaryotic cells' DNA is packed into a structure called chromatin, while eukaryotic cells' DNA is not.
d) Prokaryotic cells typically have linear DNA structures, while eukaryotic cells have circular DNA structures.
1. What causes the chromosomes to move to the opposite ends of the spindle during anaphase?
a) nuclear membranes form around each set of chromosomes and drag them apart
b) the chromosomes are pulled by the kinetochore fibers attached to the centromeres
c) the centrioles magnetically pull the chromosomes apart
d) the chromosomes are pulled by the kinetochore fibers attached to the telomeres
10. In which of these types of organisms could a scientist observe mitosis?
a) plants
b) animals
c) both A and B
d) neither A nor B
