Intron Definition. Download Full PDF Package. 37 Full PDFs related to this paper. Indeed, it can be argued that today we know a great deal about the forces that make an exon, an exon and an intron, an intron. tron (in'tron), A portion of DNA that lies between two exons, is transcribed into RNA, but does not appear in that mRNA after maturation because the intron is removed and the exons spliced together, and so is not expressed (as protein) in protein synthesis. Emanuele Buratti. Exon and intron definition in pre-mRNA splicing. Note that the introns are situated on the heterochromatin region and henceforth wrapped tightly. The word intron is derived … Intron and exon lengths can reflect the constraints imposed by splicing recognition — for example, based on whether the exon is identified through the intron or exon definition mechanism. An intron (for intragenic region) is any nucleotide sequence within a gene that is removed by RNA splicing during maturation of the final RNA product. Since its first description, researchers in this field have identified and characterized many fundamental elements and players capable of affecting the splicing process, both in a negative and positive manner. Download. An intron is a long stretch of noncoding DNA found between exons (or coding regions) in a gene. READ PAPER. Learn vocabulary, terms, and more with flashcards, games, and other study tools. In other words, introns are non-coding regions of an RNA transcript, or the DNA encoding it, that are eliminated by splicing before translation. 2013. intron-exon junction synonyms, intron-exon junction pronunciation, intron-exon junction translation, English dictionary definition of intron-exon junction.
