Which statement best summarizes the process of protein synthesis?

• Transcription of tRNA leads to the translation of DNA.

• tRNA translates mRNA to transcribe DNA to make a protein.

• DNA is transcribed to mRNA, which is then translated to make a protein.

• mRNA is transcribed to rRNA, which is then translated to make a protein.
