Question: 1 / 400

What is the primary function of RNA?

Building and repairing proteins

Regulating what enters and leaves the cell

Collecting electrons from other molecules

Transcribing genetic information

RNA serves as a messenger molecule that carries instructions from DNA for controlling the synthesis of proteins. Option A may seem correct because building and repairing proteins is a major biological function, but this is actually the primary function of proteins, not RNA. Option B is incorrect because the primary function of RNA is not to regulate what enters and leaves the cell, although RNA does play a role in regulating cellular processes. Option C is incorrect because although some RNA molecules may collect electrons, this is not the primary function of RNA. Therefore, option D is the correct answer as RNA's main function is to transcribe the genetic information from DNA and carry it to the ribosomes for protein synthesis.
