Textbook Reference: 4. Blooms Category: 1. Remembering The discovery that RNA can function as a catalyst supports which of the following statements?

Proteins were the first catalysts. Prebiotic synthesis of the four bases of RNA is not necessary for life. The prebiotic origin of small molecules was in ice on cold moons.

The prebiotic origin of small molecules occurred around hydrothermal vents. Answer: b Textbook Reference: 4. Blooms Category: 2. Understanding This evidence supports the hypothesis that a.

RNA itself cannot be a catalyst. RNA probably came from an extraterrestrial source. Which of the following statements about protocells is false? They can act as a system of interacting parts. Their interiors are separated from their exteriors. Their interiors can be chemically distinct from their exteriors. They are able to replicate nucleic acids. They can perform normal cellular metabolic reactions. Answer: e Textbook Reference: 4. Suppose that scientists developed a protocell with a membrane that allowed molecules to cross in or out of the cell.

Would this membrane serve the function of a cell membrane? Yes, because it would allow all molecules to cross either way. Yes, because it would maintain an internal environment in the protocell similar to the external environment. Yes, because it would form a complete sphere.

No, because it would not maintain an internal environment in the protocell that was different from the external environment. Both a and b Answer: d Textbook Reference: 4. Blooms Category: 4.

What is the evidence supporting the claim that ancient rocks contain the fossils of cells? The imprints of chloroplasts can be seen in the rocks.

Radioactive tracing of CO2 in the rocks shows similarities to modern cells. Microscopic examination of the rocks shows chains of cells that are similar to modern cyanobacteria. DNA analysis of the rocks shows similarities to modern cells. Pieces of RNA found in the rocks are similar to ribozymes. Answer: c Textbook Reference: 4.
