Bacteria can be genetically modified to produce human proteins by inserting human genes into plasmids.
Description
Genetic Modification Process
The human gene is isolated and cut with restriction enzymes, bacterial plasmids are cut with the same enzymes, human DNA is inserted into plasmids using DNA ligase, recombinant plasmids are introduced into bacteria, and bacteria multiply and express the human gene.
- a[1]
State why the same restriction enzymes are used to cut both human DNA and bacterial plasmid DNA.
