WebHow are Eukaryotic mRNAs modified before leaving the nucelus? - a poly (A) tail is added to the 3' end -a cap is added to the 5' end -Introns are removed by splicing -exons are joined The coding sequences of genes are found in exons pre-mRNA molecules contain intervening sequences that are not translated. WebIt still needs to be “processed,” which means that certain nucleotides are removed and others are added—at the end of this, it is an mRNA molecule, but before that, it is a pre-mRNA molecule. This occurs as the RNA molecule is leaving the nucleus. After it is processed, it is then ready for translation, which is covered in a future chapter.

WebFirst, Nirenberg synthesized an mRNA molecule consisting only of the nucleotide uracil (called poly-U). When he added poly-U mRNA to the cell-free system, he found that the polypeptides made consisted exclusively of the amino acid phenylalanine. The brief existence of an mRNA molecule begins with transcription, and ultimately ends in degradation. During its life, an mRNA molecule may also be processed, edited, and transported prior to translation. Eukaryotic mRNA molecules often require extensive processing and transport, while prokaryotic mRNA molecules do not. A molecule of eukaryotic mRNA and the proteins surr…
