Deoxyribonucleic acid (DNA) is a molecule that encodes an organism's genetic blueprint. In other words, DNA contains all of the information required to build and maintain an organism.
Chattel slavery, also called traditional slavery, is so named because people are treated as the chattel (personal property) of the owner and are bought and sold as if they were commodities. It is the least prevalent form of slavery in the world today.
Chattel slavery is still practiced in areas controlled by ISIS. In other areas slavery continues through such practices as debt bondage, serfdom, domestic servants kept in captivity, certain adoptions in which children are forced to work as slaves, child soldiers, human trafficking, and forced marriage.
