Question

Two microbes found to be very useful in genetic
engineering are
(a) Vibrio cholerae and a tailed bacteriophage
(b) Diplococcus sp. and Pseudomonas sp.
(c) Crown gall bacterium and Caenorhabditis
elegans
(d) Escherichia coli and Agrobacterium
tumefacien

Answer 1

Answer:

(d) Escherichia coli and Agrobacterium tumefacien

are the two microbes found to be very useful in genetic engineering.

Answer 2

Two microbes found to be very useful in genetic engineering are Escherichia coli and Agrobacterium tumefacien.

* These two are model organisms which are used in various genetic engineering techniques such as gene cloning, gene expression, etc.

* Escherichia coli - It has been chosen as the ideal cloning and expression vector due to its high growth rate and also ability to express proteins at a higher level.

* Agrobacterium tumifaciens- These have the ability to transfer DNA( T-DNA) to other plants swiftly and thereby has been chosen for the production of genetically transformed plants.
