Which of the following are the components/tools of recombinant DNA technology?
Correct answer: D. All of the above
- A. Gene of interest
- B. Molecular scissors
- C. Molecular glue and expression system
- D. All of the above
Explanation
Recombinant DNA technology makes use of all the molecular components mentioned above, as the main purpose of this technology, in simple words, is to cut a piece of DNA (gene of interest) from a DNA segment, using molecular scissors. This is proceeded by inserting the isolated gene into the DNA of the host organism and by using the molecular glue, it is ensured that the foreign gene segment is permanently placed into the host's DNA.
