6 DNA Embryonic stem cells (ES cells) Transplantation Clones Cloning is the moving of an organ from one body to another or from a donor site on the patients own body, for the purpose of replacing the recipients damaged or absent organ. is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. are organisms that have identical genetic material. It means that the sequence of bases in their DNA is exactly the same. are cells derived from the inner cell mass of an early – stage embryo the process of producing similar populations of genetically identical individuals that occurs in nature when organisms reproduce asexually.
