Cloning

Cloning is a phenomenon commonly referred to today. Right from 1997 when ‘Dolly’ the sheep Dolly was revealed to the world as the 1st mammal to be cloned from the cells of an adult animal. Man has been curious, perhaps disbelieving, fascinated yet apprehensive of the fact that living beings can be created in this manner. ‘Cloning’ is in the actual sense, an umbrella term which refers to ‘different processes for duplicating biological material.

The layman worldwide understands cloning as merely ‘Reproductive cloning’ which, in their opinion implied creating life replicas of the parents. However this is a rather incomplete or an incorrect opinion. There are in fact three types of cloning technologies, namely,

DNA cloning is actually ‘Recombinant’ DNA technology and alternately referred to as ‘Molecular’ cloning or ‘Gene’ cloning. It refers to a transfer of DNA fragments of interest from one organism to a self replicating genetic element. For example: A bacterial plasmid.

Reproductive cloning on the other hand is a technology used to generate an organism that has the same nuclear DNA as an already existing or previously existing


Other cloning vectors include viruses, bacteria artificial chromosomes (BAC’s) and YAC’s or Yeast Artificial Chromosomes, which carry 1MB of foreign DNA.

Finally on December 27th, 2003 ‘Clonaid’ claimed to have produced the 1st human clone named Eve. This is the 1st time a child was born who was not a genetic mix of the mother and father, but an identical copy of the mother. Eve was born to a 31 year old American who was part of the controversial UFO based cult called ‘Clonaid’ founded in Bahamans in 1997. According to the leader of this cult, mankind was created by aliens by means of genetic engineering!
