WebIn eukaryotes, pre-mRNA is transcribed by RNA polymerase II. mRNA is synthesised as pre-mRNA or primary transcript in the nucleus. It is called hnRNA or heterogeneous nuclear … WebWhen a eukaryotic gene is transcribed in the nucleus, the primary transcript (freshly made RNA molecule) isn't yet considered a messenger RNA. Instead, it's an "immature" molecule called a pre-mRNA. The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. screw-in led shop/garage light
