This document provides a definition and overview of cloning for non-technical readers. Cloning is a biological process that creates genetically identical DNA, cells, tissues or organisms through asexual reproduction. There are three main types of cloning: reproductive cloning creates animals with the same DNA as a donor, therapeutic cloning creates human embryos for stem cell research, and genetic cloning produces multiple copies of a single gene. Cloning technologies are used in agriculture, medicine, and research to study genetics and develop modified organisms, though cloning still has limitations.
