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.
Most common drug that is used worldwide is Heroin. Heroin is made from the extracts of the plant opium poppy. Heroin is taken through an injection and it directly enters the blood stream. From the blood it reaches the brain where it forces the release of endorphin hormones like serotonin.
