are preferred for recombinant dna technology
If the DNA from the different sources is cut with the same restriction enzyme, the cut ends can be joined together and then sealed into a continuous DNA strand by the enzyme ligase. In 1973, the first organism to contain recombinant DNA was engineered by Herb Boyer (UCSF) and Stanley Cohen (Stanford University). One of the most significant discoveries which allowed the development of recombinant DNA technology was restriction endonuclease. It cut double stranded DNA at specific sequences, by means of which it protects bacteria from viral infection. At the chemical level, DNA is the same whether it is taken from a microscopic bacterium or a blue whale. As a result, DNA from different organisms can be “cut and pasted” together, resulting in “recombinant DNA”. The first recombinant DNA molecule was produced in 1972 by Stanford researcher Paul Berg. Recombinant DNA technology is a technology that allows DNA to be produced via artificial means. The procedure has been used to change DNA in living organisms and may have even more practical uses in the future. A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome. Recombinant DNA is an artificial form of DNA that cannot be found in natural organisms. It is made in the laboratory by joining together genes taken from different sources. This is done by selecting and cutting out a gene at a specific point on a strand of DNA using restriction enzymes which act as molecular scissors. Vector is a DNA molecule in to which a gene is inserted to construct recombinant DNA molecule and it is also capable of replicate in a host organism. It is also otherwise known as vehicle because the vector transports the inserted gene to host organisms. Recombinant DNA technology was used for the reproductive cloning of Dolly the sheep. Recombinant DNA technology could be used to help crops resist extreme weather conditions. Recombinant DNA technology can be used for the therapeutic cloning of essential organs.

All organisms on Earth evolved from a common ancestor, so all organisms use DNA as their molecule of heredity. At the chemical level, DNA is the same whether it is taken from a microscopic bacterium or a blue whale. RESTRICTION ENDONUCLEASE: One of the most significant discoveries which allowed the development of recombinant DNA technology was restriction endonuclease. It cut double stranded DNA at specific sequences, by means of which it protects bacteria from viral infection.
