Detailed explanation-1: -What’s the difference? When scientists clone an organism, they are making an exact genetic copy of the whole organism, as described above. When scientists clone a gene, they isolate and make exact copies of just one of an organism’s genes.
Detailed explanation-2: -Cloning is a process by which identical copies of an organism are made. The copy, or clone, possesses exactly the same genetic material as the original organism. Cloning can occur naturally through asexual reproduction, wherein a single organism creates a genetically identical copy of itself.
Detailed explanation-3: -Gene cloning, which creates copies of genes or segments of DNA. Reproductive cloning, which creates copies of whole animals.
Detailed explanation-4: -11. What’s the difference between a “transgenic” animal and a “cloned” animal? A transgenic contains a foreign gene; a cloned animal contains an entire nucleus of genetic material from another individual.
Detailed explanation-5: -Cloning is a technique scientists use to make exact genetic copies of living things. Genes, cells, tissues, and even whole animals can all be cloned. Some clones already exist in nature. Single-celled organisms like bacteria make exact copies of themselves each time they reproduce.
