Splicing

RNA Splicing is simply an RNA processing where an intron (an RNA) is removed during post translational processing.

What property of RNA and DNA allows for the cutting of the molecule and removing of pieces without destroying the entire structure? Both RNA and DNA are modular structures. They consist of repeated elements: sugars and bases. Each repeated element has a 3’ and a 5 ‘ end. These repeated elements link to one another in a chain, attaching the 3’ end of one molecule to the 5’ end of another molecule. If a section of the chain is removed the two separated sections will have exposed 3’ and 5’ ends. Thus the two separated sections can easily attach to one another and form a complete chain. The modular nature of DNA and RNA allow the molecules to be modified relatively easily when necessary.
