List of introns
WebNucleotides in introns 5’ of the ATG translation initiation codon (i.e. in the 5’UTR) are numbered as introns in the protein coding sequence (see coding DNA numbering). In your example, based on a coding DNA reference sequence, the intron is present between nucleotides c.-15 and c.-14. Web22 jun. 2024 · Answer. Although introns do not encode protein products, they have very important biological functions, for example: The most important function of introns is that they allow for alternative splicing, making it possible to generate multiple proteins from a single gene. Some introns encode functional RNA molecules through further processing ...

You could use BEDOPS bedmap to map reads to introns, using 1) the --count operator to do counting of reads overlapping by your criteria; and, 2) the --indicator operator to do a true/false operation, where reads are contained entirely within the intron. For instance, to count reads that overlap introns by at least 25 bases, use ...
Web25 mei 2024 · It has been suggested that recursive splicing aids processing of long introns; however, it is also conceivable that it is easier to capture RS intermediates within long introns. The examples of cryptic RSS on the CkIIβ and CG31156 transcripts clearly deviate from canonical RSS architectural properties, i.e., they are hosted in short introns and …
