Detailed explanation-1: -Monozygotic (identical) twins are natural clones. Clones contain identical sets of genetic material in the nucleus-the compartment that contains the chromosomes-of every cell in their bodies. Thus, cells from two clones have the same DNA and the same genes in their nuclei.
Detailed explanation-2: -More narrowly, a clone can be defined as an individual organism that was grown from a single body cell of its parent and that is genetically identical to it.
Detailed explanation-3: -Clonality implies the state of a cell or a substance being derived from one source or the other. Thus there are terms like polyclonal-derived from many clones; oligoclonal-derived from a few clones; and monoclonal-derived from one clone. These terms are most commonly used in context of antibodies or immunocytes.
Detailed explanation-4: -ˈklōn. : the aggregate of genetically identical cells or organisms asexually produced by a single progenitor cell or organism. : an individual grown from a single somatic cell or cell nucleus and genetically identical to it.
Detailed explanation-5: -Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent.
