Human cloning. Human cloning is the creation of a genetically identical copy of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins. The possibilities of human cloning have raised controversies.
In the field of biotechnology, cloning is the process of creating cloned organisms of cells and of DNA fragments. The artificial cloning of organisms, sometimes known as reproductive cloning, is often accomplished via somatic-cell nuclear transfer (SCNT), a cloning method in which a viable embryo is created from a somatic cell and an egg cell.
The creation of Polly and Molly built on the somatic nuclear transfer experiments that led to the cloning of Dolly the Sheep. The crucial difference was that in creating Polly and Molly, scientists used cells into which a new gene had been inserted. The gene chosen was a therapeutic protein to demonstrate the potential of such recombinant DNA ...
From human cloning research to a scandalous downfall, the documentary tells the story of Korea’s most notorious scientist Hwang Woo-suk. Armed with a degree in veterinary science and a masters […]
In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking a denucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell. It is used in both therapeutic and reproductive cloning.
Artificial reproduction. Artificial reproduction is the re-creation of life by other than the natural means and natural causes. It involves building of new life following human plans and projects. Examples include, artificial selection, artificial insemination, in vitro fertilization, artificial womb, artificial cloning, and kinematic ...
Nuclear transfer is a delicate process that is a major hurdle in the development of cloning technology. [5] Materials used in this procedure are a microscope, a holding pipette (small vacuum) to keep the oocyte in place, and a micropipette (hair-thin needle) capable of extracting the nucleus of a cell using a vacuum.
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 ...
