Question

What happens right after transcription ends?

Answer 1

“Transcription termination. RNA polymerase will keep transcribing until it gets signals to stop. The process of ending transcription is called termination, and it happens once the polymerase transcribes a sequence of DNA known as a terminator.”

Answer 2

In Eukaryotes, maturation if the RNA into mRNA by slicing, caping and poly-adenylation. The mature mRNA is transferred to cytoplasm to be translated into proteins by ribosomes.
In Prokaryotes, translation and transcription occur simultaneously.
