Retrovirus Memes

The central dogma of molecular biology (DNA → RNA → protein) is like that friend who thinks they know all the rules until retroviruses show up at the party. Retroviruses, with their RNA genomes that convert back to DNA, just sit there smugly like that white cat, completely unbothered by your textbook definitions. They're basically the molecular biology equivalent of saying "actually..." at a department meeting. Twenty years in the lab and I still chuckle when students confidently recite the central dogma without mentioning these rebellious exceptions.
