Quizplus · Accepted Answer

Pre-mRNA, also known as precursor mRNA, is found only in the nucleus of eukaryotes. It is the initial transcript from gene transcription that is processed (spliced, capped, and polyadenylated) to form mature mRNA, which can then be exported to the cytoplasm for translation. Prokaryotes do not have a nucleus and their mRNA is not processed in the same way.
