DNA

Real World Example

Imagine trying to assemble a complicated piece of flat-pack furniture without the instruction manual. Just like that manual is essential for building the furniture correctly, DNA serves as the blueprint or instruction manual for constructing and maintaining an organism. The connection here is that both the furniture manual and DNA contain all the necessary instructions needed to create something complex and functional, guiding the assembly of parts (or cellular processes) in a specific order to achieve the final product (or living organism).
