Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).
