Question

Two bacteria found to be very useful in genetic engineering experiments are _______

(a) Nitrosomonas and Klebsiella

(b) Nitrobacter and Azotobacter

(c) Escherichia and Agrobacterium

(d) Rhizobium and Diplococcus

The question was posed to me in a national level competition.

My doubt is from Biotechnology Applications in section Biotechnology and its Applications of Biology – Class 12

Answer 1

Right answer is (c) Escherichia and Agrobacterium

For explanation I would say: Escherichia and Agrobacterium are the two most widely used bacteria for genetic engineering. Escherichia is useful for obtaining many products such as insulin while Agrobacterium is used for producing Bt crops.
