Paper 4 structured question: Genetic modification
Description
Steps in Genetic Modification
The process involves isolating the human gene using restriction enzymes, cutting bacterial plasmid DNA with the same enzymes, joining the human gene to the plasmid with DNA ligase, introducing the recombinant plasmid into bacteria, and allowing bacteria to multiply and produce the human protein.
- a[1]
State the role of restriction enzymes in genetic modification.
Aim for approximately 1 distinct marking point.
- b[1]
Identify the enzyme that joins human DNA to plasmid DNA.
Aim for approximately 1 distinct marking point.
