Introns und exons
WebA tendency for base order-determined stem-loop potential to localize to introns was apparent, but in several cases the potential was equally apparent in exons and introns (Forsdyke, 1995a). What was needed was a gene that had been under such extreme selection pressure for function that accommodation of the potential in exons would have … WebJun 19, 2024 · The stretches of DNA that do code for amino acids in the protein are called exons. During the process of splicing, introns are removed from the pre-mRNA by the spliceosome and exons are spliced back together. If the introns are not removed, the RNA would be translated into a nonfunctional protein.

WebAug 6, 2024 · An intron is a stretch of DNA that begins and ends with a specific series of nucleotides. These sequences act as the boundary between introns and exons and are … WebThe genes are split with coding regions, called exons, short for expressed regions; in between the exons the non-coding region called introns exist. Before the translation of mRNA the introns must be spliced off. Splicing is a complicated process for the cell. It must locate every intron in the primary transcript.
