  2. Human cloning - Wikipedia

    en.wikipedia.org/wiki/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. These ethical ...

    Therapeutic cloning would involve cloning cells from a human for use in medicine and transplants, and is an active area of research, but is not in medical practice anywhere in the world, as of 2024. Two common methods of therapeutic cloning that are being researched are somatic-cell nuclear transfer and, more recently, pluripotent stem cell ...

    BTX ECM 2001 electrofusion generator used for SCNT and Cloning applications. The process of somatic cell nuclear transfer involves two different cells. The first being a female gamete, known as the ovum (egg/oocyte). In human SCNT experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation.

    en.wikipedia.org/wiki/Bokanovsky's_process

    Bokanovsky's Process is a fictional process of human cloning that is a key aspect of the world envisioned in Aldous Huxley's 1932 novel Brave New World. The process is applied to fertilized human eggs in vitro, causing them to split into identical genetic copies of the original. The process can be repeated several times, though the maximum ...

    en.wikipedia.org/wiki/Nuclear_transfer

    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.

  7. Molecular cloning - Wikipedia

    en.wikipedia.org/wiki/Molecular_cloning

    Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...

    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.
