Question

Two microbes found to be very useful in genetic engineering are

• A. Crown gall bacterium and Pseudomonas sp.
• B. Escherichia coli and Agrobacterium tumefaciens
• C. Vibrio cholerae and a tailed bacteriophase
• D. Diplococcus sp. And Pseudomonas sp.

Answer 1

The correct option is B Escherichia coli and Agrobacterium tumefaciens

Two microbes found to be very useful in genetic engineering are Escherichia coli and Agrobacterium tumefaciens. The plasmids of these bacteria are used as vehicles in the transfer of foreign DNA into the host.

So, the correct option is 'Escherichia coli and Agrobacterium tumefaciens'.
