Simple Illustration of An Intron and RNA Splicing
Introns and the process of RNA splicing can be illustrated using a text example. Consider the following quotation from Groucho Marx:
- "Outside of a dog, a book is man's best friend. Inside of a dog it's too dark to read."
To make this text look more like a nucleic acid sequence, we'll simply delete all punctuation and make all of the text uppercase. This will be our "message".

If there were a single intron within this sequence, it would look something like this:

Famous quotes containing the words simple and/or illustration:
“Christina Bailey: I was just thinking how much you can tell about a person from such simple things. Your car, for instance.
Mike Hammer: Now what kind of message does it send you?
Christina: You have only one real, lasting love.
Mike: Now who could that be?
Christina: You. You’re one of those self-indulgent males who thinks about nothing but his clothes, his car, himself. I’ll bet you do push-ups every morning just to keep your belly hard.”
—A.I. (Albert Isaac)
“Each truth that a writer acquires is a lantern, which he turns full on what facts and thoughts lay already in his mind, and behold, all the mats and rubbish which had littered his garret become precious. Every trivial fact in his private biography becomes an illustration of this new principle, revisits the day, and delights all men by its piquancy and new charm.”
—Ralph Waldo Emerson (1803–1882)
