How is atmospheric nitrogen converted into a biologically useful form of nitrogen?
frutty [35]

Answer:

The atmosphere is the largest reservoir of the nitrogen as it is composed of 78% of Nitrogen. Although 78%, this is not used by the organisms directly as the nitrogen molecule exists in nature in the form of divalent joined via triple bonds.

These triple bonds require a great amount of energy to be broken and used. Only a few prokaryotic organisms called nitrogen-fixing bacteria have the capability to break these triple bonds as they contain enzymes-nitrogenase complex which converts the atmospheric nitrogen to usable forms like ammonia, nitrates and nitrites. About 92% of the atmospheric nitrogen is fixed through this way rest through thunderstorms and Haber's process.

Thus, nitrogen-fixing bacteria is the answer.

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.
Vladimir [108]

Answer:

D) The structural genes will be transcribed continuously.

Explanation:

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.  If she moves the operator to the far end of the operon, past the transacetylase (lacA) gene, the structural genes will be transcribed continuously.

A structural gene is a gene that codes for any RNA or protein product other than a regulatory factor (i.e. regulatory protein).
