RNA Splicing

A 3D animation shows the crucial RNA editing step called splicing Originally created for Learn About Spinal Muscular Atrophy ( ) TRANSCRIPT: As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons. RNA splicing begins with assembly of helper proteins at the intron/exon border
