Molecular Scissors | Restriction Endonucleases | Grade 12 | Chapter 13 topic 1 part 2 | FBISE

Molecular scissors are restriction enzymes, specifically restriction endonucleases, that cut DNA at specific recognition sequences. They are essential tools in genetic engineering and recombinant DNA technology. In this video, you will learn: What are molecular scissors? What are restriction endonucleases? How do restriction enzymes cut DNA? Recognition sequences Sticky ends and blunt ends Role of restriction enzymes in recombinant DNA technology Applications in genetic engineering This lecture is useful for Biology, Biotechnology, Genetics, Molecular Biology, FSC, MDCAT, A-Level and university students. 🔬 Key Concept: Restriction endonucleases act like molecular scissors by cutting DNA at specific sites. #MolecularScissors #RestrictionEnzymes #RestrictionEndonucleases #GeneticEngineering #RecombinantDNA #Biotechnology #MolecularBiology #GeneCloning #DNA #Biology
