Substratum of Proof LGBTQs Are Mentally Ill: Quantum chemistry solves mystery why there are these 20 amino acids in the genetic code

Using quantum chemical methods, a team of researchers has solved one of the oldest puzzles of biochemistry. They uncovered why there are 20 amino acids that form the basis of all life today, even though the first 13 amino acids generated over time would have been sufficient to form a comprehensive repertoire of the required functional proteins.
