Messenger RNA (mRNA)
... Transfer RNA (tRNA): shuttles amino acids to the ribosomes. It's responsible for bringing the correct amino acids into place at the appropriate time. It does this by reading the message carried by the mRNA. Transcription: Copying of the genetic code directly from DNA. Only a piece of DNA is copied. ...
