Splitting apart cells from a developing animal embryo before they become specialised, then transplanting the identical embryos into host mothers.

Adult cell cloning 1
The nucleus is removed from an unfertilised egg cell and the nucleus from an adult body cell, eg a skin cell, is inserted into the egg cell. An electric shock then acts as the catalyst for the egg cell to begin to divide to form embryo cells.
3 of 9
Adult cell cloning 2
These embryo cells contain the same genetic information as the adult skin cell. When the embryo has developed into a ball of cells, it is inserted into the womb of an adult female to continue its development.

Genetic engineering
Genes from the chromosomes of humans and other organisms can be 'cut out' and transferred to cells of other organisms.
5 of 9
Uses of genetic engineering
Enzymes are used to isolate the required gene. This gene is inserted into a vector, usually a bacterial plasmid or a virus.The vector is used to insert the gene into the required cells.
6 of 9
genetically modified crops (GM crops)
Crops that have had their genes modified.
7 of 9
Effect of GM crops
Resistant to insect attack or to herbicides
8 of 9
Concerns about GM crops
Effect on populations of wild flowers and insects, and uncertainty about the effects of eating GM crops on human health.
