Please could someone help me with this? I am trying to revise for my biology GCSE and I've now done two past papers that asked about animal cloning. On the first one, I described about the egg cell and the genetic material being removed etc, but the answer paper said I should have described the technique where the sperm and egg are extracted and artificially fertilised etc. So on the next paper, I described this, but the answer sheet said I should have described the original method! I am so confused. What is the difference, and how will I know which method to describe??
Many, many thanks to anyone who can help x

I believe adult cell cloning is the one where the nucleus of an adult somatic (body) cell is taken and placed in an egg cell without its nucleus. The resulting embryo - after an electric shock - is the clone of the animal from which the nucleus originated, then planted in a host mother. The other way we've learnt (on AQA) is by splitting an embryo at a very early stage before any cells have been become specialised. The resulting embryos are clones of each other, and are then planted into host mothers.
I guess telling them apart is all down to context. If you have the questions to hand, I could go into more detail.
