Biotech Definition Of Cloning : Production of genetically identical individuals that have identical nuclear DNA by asexual reproduction. Examples :- * Bacteria, Fungus * Plants-cutting-potato * Farm animals Definition Of CloningCloning Techniques: Cloning Techniques Recombinant DNA Technology * DNA cloning Reproductive Cloning Therapeutic Cloning * Embryo cloningDNA Cloning: DNA Cloning Transfer of a DNA fragment of interest from one organism to a self-replicating genetic element such as a bacterial plasmid. Plasmid – Self-replicating extra-chromosomal circular DNA molecules distinct from normal bacterial genome.DNA cloning uses: DNA cloning uses Gene therapy Genetic engineering of organism Genome sequencingReproductive Cloning: Reproductive Cloning A technique use to generate an animal that has same nuclear DNA as another currently or previously existing animal. Dolly How is reproductive cloning done ? * Somatic cell nuclear transfer (SCNT)SCNT: SCNT Starts with removal of polar body and chromosomes from an oocyte . * Enucleated oocyte . Donar cell then inserted into perivitteline space of enucleated oocyte .SCNT: SCNT Oocyte and donor cell are fused and activated by an electric pulse to begin cell division. Developed embryos transferred to surrogate females. Birth of an individual.Asexual Reproduction: Asexual ReproductionCloning Dolly: Cloning Dolly 1997 - 2003Cloning A Sheep: Cloning A SheepTherapeutic Cloning: Therapeutic Cloning Production of human embryos for use in research. Goal * To harvest stem cells that can be used to study human development and to treat disease.Stem cells: Stem cells Cells have ability to divide and give rise to both specialized cells and more stem cells. Derived from * Adults * Preimplantation embryos (Embryonic stem cells)Human Stem Cell Production: Human Stem Cell ProductionRisks Of Cloning: Risks Of Cloning Reproductive cloning expensive and highly inefficient. > 90% of cloning attempts fail to produce viable offspring. High rate of fetal loss during pregnancy. Higher rates of infection. Tumor growth . Abnormally large at birth. Die mysteriously.THANK YOU : THANK YOU You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
