Insulin Production and E. coli

The video explains that most commercial insulin is produced using genetically modified E. coli bacteria. It details the process of inserting a plasmid with the human insulin gene into E. coli, which then produces insulin in a controlled environment. The video also covers the history of insulin's discovery by Canadian researchers and the controversy surrounding a commemorative coin. The video concludes with a call to action for viewers to engage and share the content.

What is the primary source of most commercially available insulin today?

• Yeast cells

• E. coli bacteria

• Human pancreas

• Synthetic chemicals

Which of the following statements about E. coli is true?

• E. coli cannot survive in the human body.

• Most strains of E. coli are harmless.

• E. coli is only found in water.

• All strains of E. coli are harmful.

What is inserted into E. coli cells to produce insulin?

• A virus

• A protein enzyme

• A plasmid with the insulin gene

• A chemical compound

Why is E. coli a preferred host for insulin production?

• It is resistant to antibiotics.

• It grows rapidly.

• It is naturally found in the human body.

• It is easy to see under a microscope.

What happens to E. coli cells after they produce insulin?

• They are used in another process.

• They are converted into another product.

• They are destroyed or the insulin is extracted.

• They are released into the environment.

What is the final step in the insulin manufacturing process?

• Purification and packaging

What was controversial about the Canadian mint's commemorative coin for insulin's 100th anniversary?

• It featured incorrect historical dates.

• It was not released to the public.

• It did not acknowledge Banting or Best.

• It was made of gold.

What was the intention behind the Canadian mint's decision regarding the commemorative coin?

• To promote Canadian culture

• To save on production costs

• To address colonialism, patriarchy, and racism

• To honor all scientists equally

What did Frederick Banting do with his insulin patents?

• Sold them to the University of Toronto for a dollar

• Donated them to a pharmaceutical company

• Sold them for a large profit

• Kept them for personal use
