What nitrogenous base occurs in RNA but not in DNA?
Which of the following forces is the most favorable for protein folding?
Hydrophobic Interactions. Hydrophobic Effect is a major driving force for protein folding compared to other interactions such as hydrogen bonding, ionic bonding, and vander waals.
What class of organisms convert nitrogen-containing organic molecules into nitrates?
Decomposers (e.g., bacteria). Decomposers like bacteria or microbes can covert nitrogen-containing organic molecules into ammonia. Ammonia, which is a form of nitrogen-containing molecule, is subsequently converted to nitrate that plants can use to synthesize new organic compounds with nitrifying bacteria.
