Web6 aug. 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 … WebIntrons in 3′ UTRs were much less abundant than in 5′ UTRs. Though this was expected for human and mouse that have intron-dependent nonsense-mediated decay (NMD) pathways that discourage the presence of introns within the 3′ UTR, it was also true for A. thaliana and D. melanogaster, which may lack intron-dependent NMD.
