Like Y-DNA STRs, autosomal STRs are counts of repeated genetic code. As autosomal DNA recombines each generation, the number of markers shared with a specific ancestor is reduced by half each generation.
Heroin acts as a lipid soluble âprodrugâ within the brain, meaning that heroin itself is inactive but it is metabolized into an active form within the body. After crossing the blood-brain barrier, heroin is metabolized into morphine, which actively binds to opiate receptors in the brain producing the high.
Opiates (heroine,opium, codeine, morphine) metabolites codeine, morphine, and 6-acetyl-morphine.* Heroin breaks down into codeine and morphine. Codeine breaks down into morphine. 6-acetylmorphine (6-AM) is a heroin metabolite and also called 6-monoacetylmorphine (6-MAM). 6-AM metabolized to morphine.
