Question 1.
Which bacterium was first used to produce human insulin by genetic engineering?
Show hintHide hint
It is a fast-growing bacterium commonly used in laboratories.
Question 2.
Where is insulin normally made in the body, and what does it do?
Show hintHide hint
Think of the organ near the stomach that also makes digestive enzymes.
3Question 3.
Which enzyme seals the insulin gene into the opened plasmid?
- DNA ligase
- Restriction enzyme
- Amylase
Show hintHide hint
Ligare is Latin for 'to tie'.
4Question 4.
Why is an antibiotic-resistance gene included in the plasmid?
- To make the insulin stronger
- To identify the bacteria that took up the plasmid
- To kill harmful bacteria in the patient
Show hintHide hint
This is the 'selection' step.
Question 5.
A fermenter is started with 1,000 transformed bacteria that divide every 30 minutes. (a) How many bacteria are there after 5 hours, assuming ideal conditions? (b) After how many whole divisions does the population first pass one million?
Show hintHide hint
Doubling ten times multiplies the number by 1,024.
Question 6.
A classmate says, "Making insulin with genetically modified bacteria raises no ethical issues at all." Write a balanced response.
Show hintHide hint
Consider the organisms, the patients and the price.
