Q. Which type of cloning is best explained by the statement, ‘cloning produces copies of genes or segments of DNA’? Answer:
Reproductive Cloning
Notes:
The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity.
There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning.
Gene cloning produces copies of genes or segments of DNA.
Reproductive cloning produces copies of whole animals.
Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.
Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent.
