An example of a genetic engineer seen in nature is ________
Open in App
Solution
The correct option is D Agrobacterium tumefaciens
In genetic engineering, a desired part of DNA is taken and then inserted into another suitable organism for their expression. Thus, genetic engineering is an artificial process. But in nature, Agrobacterium tumefaciens (a bacterium) does this process normally. This bacterium has a plasmid, which contains a 23 base pair direct repeat sequence, called as Ti gene. Ti gene has the ability to transfer itself from Agrobacterium tumefaciens to an infected plant chromosome.
