GCSE BIOLOGY (SUMMER 2023, ANSWERED) What is cloning? Cloning is a type of asexual reproduction. It produces cells that are genetically identical to an original cell. What are clones? Clones are organisms that have identical genes. How is cloning done? 1) The nucleus is removed from an egg cell 2) The diploid nucleus is removed from an adult body cell. 3) The diploid nucleus from the body cell is placed inside the empty egg cell. The cell is then stimulated with an electric pulse to start mitot...
