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.
Heroin [diacetyl morphine] is a partially synthetic opiate compound produced when acetyl molecules are are bonded to morphine [morphine sulfate] molecules. M â¦ orphine is a naturally occurring opiate produced by and from the poppy plant.
