Detailed explanation-1: -Stem cells are cells that can replicate and can turn into any of some variety of cells. Potentially, stem cells may be useful in replenishing missing or defective cell populations in an organism. Cloning (in this context) involves growing a new organism from a single cell of an old organism.
Detailed explanation-2: -No. Researchers haven’t been able to successfully perform therapeutic cloning with humans despite success in a number of other species. However, in recent studies, researchers have created human pluripotent stem cells by modifying the therapeutic cloning process.
Detailed explanation-3: -Genomes can be cloned; individuals cannot. In the future, therapeutic cloning will bring enhanced possibilities for organ transplantation, nerve cells and tissue healing, and other health benefits.
Detailed explanation-4: -Embryonic stem cells and therapeutic cloning Such cells can be cultured indefinitely as embryonic stem cell lines. Existing human embryonic stem cell lines have been derived from in-vitro fertilized, early-stage human embryos, that would have perished without implantation into a uterus.
