Genetic Engineering and Immune System

The video discusses genetic engineering's role in producing insulin, especially for Type 1 diabetes. It explains how genetic engineering allows bacteria to produce human insulin, replacing the need for animal-derived insulin. The video also covers the universality of the genetic code, the use of restriction enzymes and ligase in genetic engineering, and the broader applications of genetic engineering in agriculture and research.

What is the primary issue with the immune system in type 1 diabetes?

• It attacks the body's own pancreas cells.

• It produces too much insulin.

• It becomes inactive.

• It fails to recognize viruses.

Why was obtaining insulin from animals not an ideal solution?

• It produced low-quality insulin.

• It was a slow process.

• It required the slaughter of animals.

• It was too expensive.

What is the shape of DNA?

• A straight line

• A twisted ladder

• A circle

• A square

What role do proteins play in the body?

• They provide energy.

• They transport oxygen.

• They are the building blocks of muscles and other functions.

• They store genetic information.

What makes genetic engineering possible across different organisms?

• The unique genetic code of each organism

• The universality of the genetic code

• The size of the organism's DNA

• The speed of DNA replication

What is the function of restriction enzymes in genetic engineering?

• To destroy unwanted DNA

• To replicate DNA

• To cut DNA at specific sites

• To paste DNA fragments together

Why is E. coli used in the production of human insulin?

• It is easy to grow and manipulate.

• It is resistant to antibiotics.

• It is the only bacteria that can be genetically modified.

• It naturally produces insulin.

What is the role of ligase in genetic engineering?

• To degrade DNA

• To join DNA fragments

• To replicate DNA

• To cut DNA

What are some applications of genetic engineering beyond insulin production?

• Producing fossil fuels

• Developing genetically modified crops

• Creating new species

• Building artificial organs

What is a common concern regarding genetic engineering?

• It is not scientifically proven.

• It is too expensive.

• It may not be effective.

• It could affect food safety.
