Answer:
The correct answer is recombinant DNA technology.
Explanation:
In recombinant DNA technology, the formation of the molecules of DNA is done artificially by combining the DNA from distinct sources. In 1973, Cohen and Boyer separated the genes, which codes for rRNA from the African clawed frog DNA and administered it into the E.coli bacteria DNA. At the time of transcription, the bacteria generated frog rRNA, that is, the initial genetically amended organism.
The procedure used by Cohen and Boyer is known as gene transfer.
What is gene transfer?
The introduction of a new DNA into an existing organism's cell via vectors like plasmids and modified viruses is called gene transfer.
There are three ways of gene transfer : transduction, bacterial conjugation and natural transformation.
By gene transferring doctor, a healthy copy of gene into a body.
One gene produce many similar copy of genes.
Thus, in the given case, there is gene transfer is done between African frog and bacteria.
