Messenger RNA Questions And Answers Question 1. What are intervening sequences or introns? What is mRNA splicing? Answer: Untranslated sequences that interrupt the coding sequence of a transcript and that are removed before translation begins. Removal of introns. Question 2. Many eukaryotic genes contain noncoding introns that separate the coding … [Read more...] about Messenger RNA Questions And Answers
RNA Editing Notes
RNA Editing In the late 1980s, still, another quite unexpected form of post-transcriptional RNA processing was discovered in several organisms. In this form, referred to as RNA editing, the nucleotide sequence of a pre-mRNA is changed before translation. As a result, the ribonucleotide sequence of the mature RNA differs from the sequence encoded in the exons of the DNA … [Read more...] about RNA Editing Notes
Rna Processing And Modifications Notes
Modification And Processing Of mRNA Most eukaryotic mRNAs undergo a quite complicated series of modifications and processing events before translation occurs. These include: Chemical modification to the two ends of the mRNA molecule (Capping). Polyadenylation Removal of introns (Splicing). In a few special cases, alterations to the nucleotide sequence of the mRNA … [Read more...] about Rna Processing And Modifications Notes
