Film summary
A look at natural cloning and the main artificial cloning techniques devised by man, including embryo transplant and fusion cell cloning.Key facts
- Cloning occurs naturally in asexual reproduction in plants and animals, and in human reproduction when genetically identical twins are produced.
- Artificial cloning techniques include: embryonic cloning and fusion cell cloning.
- Embryonic cloning involves separating the cells of an embryo to create several identical embryos.
- Fusion cell cloning involves removing the nucleus of an egg and replacing this with a cell nucleus of a donor.
Transcript
Cloning means making an identical copy.
Clones are genetically identical and occur naturally in asexual reproduction in bacteria and in plants.
Cloning can also occur in human reproduction, when a fertilized egg cell breaks in half, resulting in identical twins.
With advances in biology, it is now possible to perform cloning in the …
