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.
The first official legal recognition of chattel slavery as a legal institution in British North America was in Massachusetts, in 1641, with the Body of Liberties. Slavery was legalized in New Plymouth and Connecticut when it was incorporated into the Articles of the New England Confederation (1643).
