The term 'identical being' can be described as a CLONE, which is a five-letter word. A CLONE is an organism that is genetically identical to another organism, meaning it has the same DNA sequence. Clones are created through a process called cloning, which involves taking a cell from one organism and using it to create a new organism with the same genetic makeup. Cloning has been used for many purposes, including medical research, agricultural production, and even creating new species of animals.
