What is made at the end of transcription?

At the end of transcription it's either DNA or RNA try googling it

At the end of transcription, all RNA molecules needed for later stages of protein synthesis are made. This includes mRNA, tRNA and rRNA. The mRNA molecule acting as a blueprint for the genetic construction of a specific protein from the encoded information obtained from transcribing a segment of DNA is more or less the main event occurring in transcription.
