WebMay 30, 2003 · We show here that intron-poor eukaryotes for which genome data is available have a 5′ bias in the position of their introns within genes. This decrease in introns toward the 5′ end of the gene is more pronounced with increasing intron paucity. We argue that this asymmetry is more consistent with models of intron loss from intron-poor … 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 known as splice sites. The recognition of the boundary between coding and non-coding DNA is crucial for the creation of functioning genes. In humans and most other vertebrates …
