Splicing variants at the 3′ end of the gene characterize ... Several methods of RNA splicing occur in nature; the type of splicing depends on the structure of the spliced intron and the catalysts required for splicing to occur. The word intron is derived from the terms intragenic region, and intracistron, that is, a segment of DNA that is located between two exons of a gene. The term i… impacthero oneplus nord n20 5g cases
