Answer:
C
Explanation:
The process in which cells make proteins is called protein synthesis. It actually consists of two processes: transcription and translation. Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
We discard answer A, because the process in which ribosomes assemble aminoacids to make proteins is called translation.
We can also discard answer D, as transcriptions occurs in the nucleus.
Answer C is correct, as it's true that mRna is made from DNA in the nucleus during transcription.
