People sometimes like to display bumper stickers that relate to their trade or field of study. for example, a chemist may have a bumper sticker that says "it takes alkynes to make the world." then, chemists or other people who know that an alkyne is a molecule that contains carbon atoms joined by a triple bond get a nice little chuckle out of the play on words. use your knowledge of dna replication to write a bumper sticker.
