Animal Applications of Biotechnology

What is the Bt gene?

• Obtained from Agrobacterium tumefaciens

• Obtained from Bacillus thuringiensis

• Obtained from European corn borer

• Obtained from Bacillus thermofilus

• Is designed in the lab

What happens when the European corn borer feeds on corn containing the Bt gene?

• The Bt gene is transferred to the borer.

• The Bt protein penetrates and collapses the cells lining the gut and the insect dies.

• The European corn borer becomes resistant to the Bt gene.

• The Bt gene has no effect on the European corn borer.

What is ELISA primarily used for in veterinary medicine?

• Gene therapy in animals

• Detection of a large variety of animal viral and bacterial diseases

• Production of engineered protein products

• Accurate quantification of gene expression levels

What does qPCR stand for in the context of veterinary diagnostics?

• Quality Polymerase Chain Reaction

• Quantitative Polymerase Chain Reaction

• Quick Polymerase Chain Reaction
