EXAM REVIEW
Viruses do not exhibit characteristics of cells as defined by the cell theory. The most likely reason why
viruses are excluded from the cell theory is that: - answer ✔✔-viruses utilize host cell enzymes for
reproductive processes
What would be a way to determine if a plasma membrane protein operates as a rotating carrier during
ion transportation? - answer ✔✔-Attaching a large polar antibody to the portion of the carrier protein
facing the cell exterior and observing the effect on the ion transport rate
Which characteristic distinguishes viruses from encapsulins - answer ✔✔-Genetic material
Which of the following cellular processes would most likely lead to increased genetic variation in a
population of organisms? - answer ✔✔-Synapsis involving two homologous chromosomes.
Which of the following could have facilitated the evolution of modern human adults from chimpanzee
ancestors?
I. Behavioral isolation
II. Hybrid breakdown
III. Convergent evolution - answer ✔✔-I and II only
Assume a single-celled organism was discovered in water above 100°C. On closer inspection, it is
determined that this organism was previously classified under the Archaea domain. Given this
information, this organism most likely has: - answer ✔✔-circular chromosome
