Consider the following statements I. $Bt$ toxin gene has been cloned from the bacteria II. Genetic engineering works only on animals and has not yet been successfully used on plants III. Strains of $Bacillus\ thuringiensis$ are used in producing bioinsecticidal plants Which of the statements given above are correct?

Question

Dr. Abubacker · Accepted Answer

Specific Bt toxin genes obtained from bacteria Bacillus thuringiensis are used in several crop plants like cotton. It is easier to produce transgenic plants than animals. A single cell in most plant species can regenerate a whole plant. Thus, a single genetically engineered cell can produce a new plant with new traits. Bacillus thuringiensis forms the protein crystals which contains a toxic insecticidal protein
