Cloning Abd Genetic Engineering Flashcards
How do you clone a plant with cuttings?
1) take cuttings from a PARENT PLANT
2) the cuttings are kept in moist conditions until ready to plant
3) plant them and the plant has been cloned.
How do you clone a plant with tissue culture?
1) a few plant cells are put in a growth medium with hormones
2) they grow into new plants // clones
Benefits of cloning plants?
Fast
Cheap
How are animals cloned?
By embryo transplants
How do you clone animals by embryo transplants?
1) the sperm from the best animal is taken and the egg from the best animal taken. They are then artificially fertilised
2) the embryo develops and then splits forming clones
3) the cloned embryos are then implanted and then given birth to
4) the clones have been made
How do you clone through adult cell cloning?
1) an unfertilised egg is taken and the nucleus is removed
2) a complete set of chromosomes are taken from an adult body cel.
3) the nucleus of the adult body cell is inserted into the egg cell
4) the egg is stimulated by an electric shock
5) the embryo (ball of cells) is implanted into an adult female and grows - cloning the original adult body cell
Name some issues surrounding cloning?
The population is closely related so a new disease could wipe them all out
Animals may not be as healthy
Can be unsuccessful
Benefits of cloning?
Better understanding of development of embryos and ageing
Also helps to preserve endangered species
What are the two ways to clone plants, what are they?
Cuttings
Tissue culture
