The toxin proteins, isolated from Bacillus thuringiensis , coded by which of the following genes would control cotton bollworms and corn borer, respectively ?

Options

  1. AcryIAc and cryIAb
  2. BcryIAc and cryIIAb
  3. CcryIIAb and cryIAc
  4. DcryIAc and cryIIIAb

Correct answer

A. cryIAc and cryIAb

Step-by-step solution

The toxin proteins encoded by the genes cryIAc and cryIIAb control the cotton bollworms. The toxin protein encoded by the gene cryIAb controls the corn borer. Therefore, the genes that control cotton bollworms and corn borer respectively are cryIAc and cryIAb . Answer: cryIAc and cryIAb
