Plus Two Biology - Chapter 11: Biotechnology Principles & Processes (Part 2)
🧬 Topic: Insertion of Recombinant DNA into the Host (Competent Host)
In this video, we continue our journey into Biotechnology! In Part 1, we made the Recombinant DNA. Now, in Part 2, we learn how to put that DNA inside the bacteria or cell.
I have explained the 4 major methods in simple Malayalam so you never forget them for your Board Exams and NEET.
⏱️ What You Will Learn in This Video: ✅ Competent Host: Why bacteria doesn't accept DNA easily? ✅ Chemical Method: Role of Divalent Cation (Calcium) & Ice. ✅ Heat Shock Method: The "Hot & Cold" trick. ✅ Micro-injection: Injecting DNA directly (Animal Cells). ✅ Biolistics / Gene Gun: Shooting DNA with Gold/Tungsten (Plant Cells). ✅ Disarmed Pathogen: Using Agrobacterium as a delivery boy.
💡 Exam Tip: The difference between "Micro-injection" and "Gene Gun" is a frequent 2-mark question. Pay attention to the examples!
