- The table shows the steps, timeline and efficiency for the production of fertile transgenic corn (Zea mays). Immature corn embryos were transformed with Agrobacterium tumefaciens to obtain resistance to bialaphos, a chemical herbicide.
(a) Describe the use of A. tumefaciens as a vector in the production of transgenic corn. [2]
(b) Calculate the efficiency in the production of transgenic corn, assuming all transgenic seeds germinated. [1]
(c) State another example of the use of A. tumefaciens in herbicide resistance. [1]
