DNA

Real World Example

Imagine trying to assemble a piece of flat-pack furniture without the instruction manual. Just like how you rely on the manual to guide you through each step to build the furniture correctly, DNA serves as the instruction manual for building and maintaining an organism. In this analogy, each piece of furniture corresponds to a specific part of an organism, and the DNA's genetic information provides the step-by-step guide needed to assemble these parts accurately, ensuring everything functions as it should.
