5.14 Human insulin production question 1
[Maximum number: 3]
Insulin is a hormone produced in the human body.
The insulin now used for injections is obtained from bacteria that have been genetically modified.
Describe how these bacteria are genetically modified to produce human insulin.
A description that makes reference to three of the following points:
- human gene / allele / DNA (for insulin) gene from pancreas
- (cut with) restriction enzyme
- (join with) ligase
- vector / plasmid
not just
gene
so gene for
insulin or human gene
or gene
from
pancreas ok
