Answer: Carrier of foreign DNA into a host cell (e.g., plasmid or virus).
- A A type of organism that is itself the target of genetic modification
- B Carrier of foreign DNA into a host cell (e.g., plasmid or virus)
- C A restriction enzyme that simply cleaves the target DNA strand
- D A type of antibody used specifically in diagnostic laboratory assays
Correct answer: B. Carrier of foreign DNA into a host cell (e.g., plasmid or virus)
Explanation: A vector (plasmid, bacteriophage, or viral vector) carries the foreign gene into the host cell for replication and expression.
Recombinant DNA technology: a gene of interest and plasmid are cut by the same restriction enzyme, ligated into a recombinant plasmid, and introduced into a host cell.
