Detailed explanation-1: -The molecular and cellular techniques of biotechnology allow researchers to genetically engineer organisms, modifying them to achieve desirable traits. Cloning may involve cloning small DNA fragments (molecular cloning), or cloning entire organisms (reproductive cloning).
Detailed explanation-2: -Cloning is a method to produce an organism which is identical to the other organism. The plasmids are the small extra-chromosomal DNA present in the bacteria which are commonly used as a cloning vector. The process of cloning is performed for obtaining identical copies of the same cell.
Detailed explanation-3: -Cloning, the process of generating a genetically identical copy of a cell or an organism. Cloning happens all the time in nature-for example, when a cell replicates itself asexually without any genetic alteration or recombination.
Detailed explanation-4: -Cloning in biotechnology is intentional cloning of an organism or molecular cloning of DNA fragments. In biotechnology scientists mainly use three types of cloning, known as reproductive cloning, therapeutic cloning and DNA cloning.
