Detailed explanation-1: -Scientists took udder cells from Dolly’s DNA mother. They let the cells multiply and then they stopped the process when they had divided enough. 2. They took an egg cell from a different sheep and removed the nucleus.
Detailed explanation-2: -How are animals cloned? In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal’s somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.
Detailed explanation-3: -DNA cloning is used to create a large number of copies of a gene or other piece of DNA. The cloned DNA can be used to: Work out the function of the gene. Investigate a gene’s characteristics (size, expression, tissue distribution)
