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.
The primary component of opium is 12% morphine which is an alkaloid that is often processed chemically to produce illegal drugs such as heroin. Codeine and other non-narcotic alkaloids are also found in the latex that is derived from the opium poppy plant.Opium is the main component of morphine. Traditionally, opium was obtained from the latex of the poppy plant by scoring the seed pods by hand and allowing the latex to leak out and dry up.he primary component of opium is 12% morphine which is an alkaloid that is often processed chemically to produce illegal drugs such as heroin.
