Question
Explain the following terms with respect to rDNA technology
- passanger DNA
- Chimeric DNA
- Transformed cell
- restriction site

Solution
- Passenger DNA: A DNA fragment containing desired gene that is isolated and selected for cloning is called foreign DNA or passenger DNA.
- Chimeric DNA: The combination of vector DNA and foreign DNA is called Recombinant DNA or Chimeric DNA.
- Transformed cell: The host/ competent cell which has taken up rDNA is called transformed cell.
- Restriction site: The particular sequence of nucleotides on DNA where a restriction enzyme cuts the two strands of DNA is called recognition or restriction site.
