Genetic Modification: Processes and Applications

The video tutorial explains genetic modification, focusing on genetic engineering to produce insulin using bacteria. It details the process of isolating and inserting genes into plasmids, using industrial fermenters for large-scale production, and employing viruses as vectors. The tutorial also covers genetic modification in plants to enhance crop efficiency.

What is the primary goal of genetic modification?

• To create new species

• To introduce desirable traits into an organism

• To increase the lifespan of organisms

• To eliminate all genetic diseases

Which enzyme is used to cut DNA molecules during genetic modification?

• Polymerase

• Ligase

• Restriction enzyme

• Helicase

What is a plasmid's role in genetic engineering?

• It destroys harmful genes

• It serves as a vector to carry recombinant DNA

• It acts as a nutrient source

• It provides energy for the cell

What is a transgenic organism?

• An organism with DNA from multiple sources

• An organism that cannot reproduce

• An organism with no genetic material

• An organism that is resistant to all diseases

Why are air bubbles introduced into an industrial fermenter?

• To add nutrients

• To provide oxygen for bacterial respiration

• To cool down the fermenter

• To remove waste gases

How can viruses be used in genetic modification?

• By increasing the size of plant cells

• By destroying harmful bacteria

• By delivering recombinant DNA into cells

• By acting as a nutrient source

What is a benefit of genetically modifying plants?

• They can produce natural fungicides

• They become immune to all pests

• They require no water

• They can grow without sunlight
