The Building Blocks

DNA: The Blueprint of Life
DNA, or deoxyribonucleic acid, consists of four nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). The order of these bases forms the code for cell functions, from protein creation to eye color. During cell division, DNA replicates, passing genetic info like sharing game secrets.

RNA: The Messenger
RNA, or ribonucleic acid, is DNA's trusty sidekick! While DNA stays in the nucleus, RNA acts as a messenger, using ribose sugar and uracil (U) instead of thymine. The primary type, mRNA, carries DNA's code to ribosomes, the protein-making factories.

In short, DNA holds genetic information, while RNA expresses it, making life possible—how cool is that?
