Biology.Once upon a time, there was a mischievous phosphate group who had nothing to do aside from random collisions in the cytoplasm. After filing down its sharp edges, and bumbling along indolently, he saw the vain sugar group rolling towards him.
Phosphates, for some reason, don't like sugar groups. So Mister phosphate stuck his chemical-bond-thingy leg out and tried to trip the sugar group.
Unfortunately, the sugar group, being excessively narcissistic, thought Mister phosphate was trying to seduce her with his sexy leg. She clung onto his leg, to Phosphate's disgust. Multiple attempts to shake off the clingy and whiny sugar group PHAILED, for miss sugar only persisted in her attempts to massage Mister's phosphate's leg with her flat chest.
A blinding light filled the sol state sky and the base was created. Now the bisexual base, being the horny sex-deprived angular thing (he?she?it?) is, thought miss sugar and Mr phosphate was having some really hot hentai sex, so he/she/it sauntered over and sodomised miss sugar.
This resulted in the formation of a S&M-obsessed nucleotide, which has been since torturing innocent Biology students by forcing them to remember its structure for the Biology exams or face the horrors of the-land-of-no-A1s. The end.

There is no point to this post except to help me remember the structure of the nucleotide. It's scientifically proven that one can remember better where sex, random facts and colours are involved, so here goes.
