Cloning And stem Cells

Cloning And Stem Cells:

  • Cloning is the process by which genetically identical individuals are produced.
  • Cloning happens in nature by the biological mechanisms of asexual reproduction in bacteria, insects and plants.
  • Cloning can also be performed artificially by copying fragments of DNA (molecular cloning) or cells (cell cloning) or organisms.
  • Mammals, which reproduce sexually, cannot clone naturally,. Mammals inherit genetic material half each from both parents, meaning that the progeny is never an identical replica of the parent. Natural clones in mammals are confined to the production of identical twins.
  • The first vertebrate to be cloned was a tadpole by Robert Briggs (USA) and Thomas King (USA) in 1952.
  • Stem Cells:

    Overview

  • Stem cells are cells that can renew themselves.
  • Stem cells renew themselves through mitotic cell division and can differentiate into a diverse range of specialised cell types.
  • Stem cells are found in most multi-cellular organisms.
  • There are two types of stem cells in mammals - Embryonic stem cells and Adult stem-cells.
  • Stem cells are mainly found in blood from the umbilical cord and the bone marrow.
  • Due to their self-renewing nature, stem cells are very important for treatment of disease.
