The process of cloning a particular farm animal using SCNT is relatively the same for all animals. The first step is to collect the somatic cells from the animal that will be cloned. The somatic cells could be used immediately or stored in the laboratory for later use. [ 17 ]
Molecular cloning generally uses DNA sequences from two different organisms: the species that is the source of the DNA to be cloned, and the species that will serve as the living host for replication of the recombinant DNA. Molecular cloning methods are central to many contemporary areas of modern biology and medicine. [2]
However, the cloning was done from early embryonic cells, while the sheep Dolly in 1996 was cloned from an adult cell. [82] Megan and Morag were sheep cloned from differentiated embryonic cells in 1995. Dolly (1996–2003), first cloned mammal from adult somatic cells. She had six lambs. [83]
Cloning animals requires procedures that can cause pain and distress, and there can be high failure and mortality rates.” Being able to produce genetically identical monkeys could be useful ...
The most common application of recombinant DNA is in basic research, in which the technology is important to most current work in the biological and biomedical sciences. [13] Recombinant DNA is used to identify, map and sequence genes, and to determine their function. rDNA probes are employed in analyzing gene expression within individual cells ...

"Therapeutic cloning" refers to the potential use of SCNT in regenerative medicine; this approach has been championed as an answer to the many issues concerning embryonic stem cells (ESCs) and the destruction of viable embryos for medical use, though questions remain on how homologous the two cell types truly are.
Most other cells cannot divide indefinitely as after a few cycles of cell division the cells stop expressing an enzyme telomerase.The genetic material, in the form of deoxyribonucleic acid (DNA), continues to shorten with each cell division, and cells eventually stop dividing when they sense that their DNA is critically shortened.
