clonning Right or wrong ?

It is important that we discuss this issue here.all your comments are most welcome.Cloning attempts occurred as early as 1952, and the first successful transfer of embryonic cells occurred in 1970 Ian Wilmut, the scientist famous for the "Dolly" cloning experiment has paved the way for a completely different thought. There were other organisms that were cloned but what made "Dolly" unique was that instead of cells being taken from an embryo "Dolly" was created by using DNA from an adult ewe. The process of cloning was discovered to be simpler than what was thought. The first step is to take the cells from the udder of a Finn Dorset ewe and place them in a culture with low concentrations of nutrients causing it to starve and ultimately stop cell division and active genes. While this is occurring an unfertilized egg cell is taken from a Blackface ewe with its DNA filled nucleus taken out leaving a nucleus free egg cell that will later produce an embryo . Next with the aid of an electric pulse the cells from the udder of a Finn Dorset ewe and the unfertilized egg cell with no nucleus is fused together to begin cell division which will later turn into an embryo which will be placed in the uterus of another Blackface ewe. Eventually the Blackface ewe will give birth to a new genetically identical Finn Dorset ewe. With the creation of "Dolly" the doors of human cloning has opened the controversy and complications of cloning. First we need to know both the sides of this coin to discuss this issue.
do we need to play God ? If yes, how far and how long and to what extent ?
