DNA to Protein: Life’s Instruction Manual

Your entire existence is basically a four-letter code running on repeat inside your cells.

Think of DNA as the master blueprint locked in a vault. It is way too important to leave the nucleus,

so it sends a cheap copy called RNA to get the job done. This message hits up a ribosome,

which acts like a biological 3D printer. It reads the instructions to build proteins,

the actual workhorses that make your heart beat and hair grow. Sometimes the code gets a typo,

called a mutation, but that is just nature remixing the recipe. It is wild that

a microscopic twisted ladder is the only reason you are alive right now.
