Modern cloning techniques Flashcards
What are the 3 main modern cloning techniques?
1) Tissue culture
2) Embryo transfer
3) Adult cell cloning
Describe tissue culture?
Take a small group of cells from either the leaf or the stem or roots. Start to encourage the cells to grow by putting them into agar. Carry out the process using aseptic technique. Then you end up with small plants with roots, stems and leaves. put plants into individual pots of soil to grow.
what does agar contain?
Vitamins, sugars and hormones
Give an advantage of using tissue culture?
You can create thousands of clones of that particular plant.
Give an advantage of using tissue culture?
It is expensive
Describe embryo transfer?
Take an egg cell and sperm cell. Then fuse them together to produce a fertilised egg. Then the egg cell will grow into an embryo a ball of specialised cells. Split the embryo into more smaller balls of cells. Take a small ball of cells and implant it into one of the host mothers.
Describe adult cell cloning?
Take a skin cell from sheep A. Take an egg cell from sheep B. Next take the nucleus from sheep A’s cell and implant it into sheep B’s egg cell. Give it a small electric shock. Implant it into the new embryo into another host mother sheep C. You have clone of sheep A.
