Intron

Real World Example

Imagine you're reading a novel, and you come across several pages filled with notes from the author that don't advance the plot. These notes, while not part of the story, provide important context or background that could help understand the characters or setting. Similarly, in our DNA, introns are like those notes – they don't directly code for proteins (the 'plot' of cellular function) but can play crucial roles in regulating gene expression or evolution. Just as those extra pages in the novel help give depth or context to the narrative, introns, although they don't code for amino acids, contribute to the overall complexity and regulation of our genetic 'story'.
