Operon's Reign

[Verse 1] In the cell’s tiny world, there’s a story to be told, Of genes and proteins, and how they unfold. Lactose operon, you’re the star of the show, Regulating enzymes, making lactose flow. [Chorus] Oh, lactose operon, you turn the switch on, When lactose is present, you help it move along. With repressor and promoter, you control the game, In the world of genetics, you’ve earned your fame. [Instrumental] [Verse 2] When lactose is absent, the repressor binds tight, Blocking RNA polymerase, keeping genes out of sight. But when lactose appears, it binds to the repressor, Releasing the genes, making the process lesser. [Long Instrumental, but the Bridge is worth it] [Bridge] Inducer, operator, and those structural genes, Working together in molecular scenes. From Z to Y to A, the enzymes are made, Breaking down lactose, in a sweet cascade. [Chorus] Oh, lactose operon, you turn the switch on, When lactose is present, you help it move along. With repressor and promoter, you control the game, In the world of genetics, you’ve earned your fame. [Outro] So here’s to the operon, in the cell’s grand design, A marvel of nature, so intricate and fine. Lactose operon, you’re a genetic delight, In the dance of life, you shine so bright.
