WebNov 10, 2024 · We show that increased chromatin accessibility, as revealed by nucleosome-free regions, contributes substantially to the retention of introns in a cell-specific manner. We also confirm that intrinsic characteristics of introns are key for them to evade splicing. This study suggests an important role for chromatin architecture in IR regulation. WebOct 17, 2012 · Discussion. Using the introns derived from nearly 20000 intron-containing genes, we analyze the sequence features associated with transcriptional regulation. The various characteristics of the first introns within these genes suggest that the first introns are most likely to be involved in transcriptional regulation. An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word intron is derived from the term intragenic region, i.e. a region inside a gene. The term intron refers to both the DNA sequence within a gene and the corresponding RNA sequence in RNA transcripts. The non-intron sequences that become joined by this RNA processing to form the mature RNA are called exons. springfield massachusetts allergy report
