How universality of genetic code create the recombinant DNA

Question

How does the universality of genetic code create the recombinant DNA technology possible?

Answer 1

The universality of genetic code refers to the fact that all living-beings have their protein synthesis machinery functioning according to similar principles of transmission, storage, and recognition of information, comprising translation of mRNA codons. This fact makes probable the exchanging of genes or gene fragments among various organisms and secures that such genes continue to command protein synthesis.

This universality, for illustration, makes feasible the insertion of a fragment of human DNA having a gene for the production of a specified protein into the genetic material of bacteria. As the bacterial transcription and translation systems work in similar manner as the correspondent human systems do, the bacteria will start to synthesize the human protein associated to the inserted DNA fragment. There are industries which generate human insulin (for use by the diabetic patients) in this manner, synthesized by bacteria with modified DNA. When the genetic code was not universal this type of genetic manipulation would be not possible or very hard to accomplish devoid of new technological progresses.
