The answer is the third one (C): mRNA.

Explanation for each option:

  • Ribosomal RNA (rRNA): This type of RNA is a component of ribosomes, which are the cellular structures where protein synthesis occurs. It does not carry genetic information from the DNA to the cytoplasm.

  • tRNA (transfer RNA): This type of RNA is involved in the translation process by bringing amino acids to the ribosome to be added to the growing protein chain. It does not carry the genetic code from the DNA.

  • mRNA (messenger RNA): This is the correct answer. mRNA is the RNA copy of DNA that is synthesized during transcription. It carries the genetic information from the DNA in the nucleus to the cytoplasm, where it serves as a template for protein synthesis.

  • RNA polymerase: This is an enzyme that synthesizes RNA from a DNA template during transcription. It is not an RNA molecule that carries genetic information.

In summary, mRNA is the RNA copy of DNA that leaves the nucleus and travels to the cytoplasm to make proteins.
