Question

Which of the following is not an example of genetic engineering that is currently being used?

• A. Bacteria have been engineered to clean up oil spills.
• B. The Tasmanian tiger has been brought back from extinction from DNA found in the species that has subsequently been using for cloning.
• C. Goats are engineered to produce milk containing spider silk.
• D. Rabbits are engineered to glow green under black light.

Answer 1

The correct option is A Bacteria have been engineered to clean up oil spills.

Some bacteria feed on crude oil as a source of energy, these bacteria are capable of breaking down crude oil.

For example, Colwellia, Cycloclasticus, Alcanovorax etc.

The genes that are present in these bacteria are transferred to other strains of the same species through horizontal gene transfer.

Which can also be inserted by genetic engineering into other bacteria for clearing oil spills.

So, the correct answer is 'Bacteria have been engineered to clean up oil spills'
