Which of the following statement is incorrect?

The correct answer is Option (3)- Human insulin is being commercially produced from transgenic species of Agrobacterium tumefaciens.

Explanation:

Human insulin is not produced from transgenic species of Agrobacterium tumefaciens. Instead, human insulin is commonly produced using recombinant DNA technology in bacterial cells, particularly Escherichia coli (E. coli. These cells are modified to carry and express the human insulin gene, allowing them to produce insulin in large quantities for medical use.

The other statements are correct:

• Human protein used to treat emphysema is alpha-1 antitrypsin, which helps protect the lungs from damage caused by enzymes.
• Rosie, the first transgenic cow, produced human protein-enriched milk by introducing a human alpha-lactalbumin gene.
• Cry I Ab endotoxins obtained from Bacillus thuringiensis are effective against corn borers because they are toxic to certain insect pests and are commonly used in genetically modified crops like Bt corn to provide resistance against these pests.
