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. WebSep 20, 2024 · In eukaryotes, the heterogeneous nuclear RNA that makes up the mRNA is made in the nucleus (hnRNA). When hnRNA is broken down, the functional mRNA is released. This mRNA goes into the cytoplasm to help make proteins. mRNA is made up of molecules that are big and have a short half-life.
