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.
Starts with poppy-based raw material (codeine, morphine, thebaine) and chemically alter these in the lab to come up with hydromorphone, hydrocodone, oxycodone, oxymorphone, desomorphine, diacetylmorphine (heroin), etc. Opioid, fully synthetic: Fentanyl, pethidine, methadone, tramadol, dextropropoxyphene, buprenorphine (suboxone), etc. Created in lab with no need for raw material derived from the poppy.
