In a mature functional mrna of eukaryotes

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. WebApr 15, 2024 · The mature mRNA molecule is then transported out of the nucleus and into the cytoplasm for translation. Read also: COMPARE AND CONTRAST MULTIPLE CHOICE TEST. Differences in mRNA Function: The function of mRNA in prokaryotes and eukaryotes is also different. In prokaryotes, mRNA is usually polycistronic, meaning that it contains …
