Intron - Wikipedia

WebIn most eukaryotic genes, coding regions (exons) are interrupted by noncoding regions (introns). During transcription, the entire gene is copied into a pre-mRNA, which includes exons and introns. During the process of RNA splicing, introns are removed and exons joined to form a contiguous coding sequence. WebCancer can be caused by many different mutations in cells. Some of these mutations are the result of incorrect intron excision by splicing enzymes. Introns are extra nucleotide … first time home buyer loan salem
