FAQs on Working of Restriction Endonucleases Video Lecture - Biology for Grade 12
| 1. How do restriction endonucleases work? |  |
Ans. Restriction endonucleases are enzymes that recognize specific DNA sequences and cleave the DNA at those sites. They act as molecular scissors, cutting the DNA into fragments. This process is important in various molecular biology techniques, such as DNA cloning and genetic engineering.
| 2. What is the role of restriction endonucleases in DNA cloning? | |
Ans. Restriction endonucleases are crucial in DNA cloning as they allow the manipulation and modification of DNA molecules. By cutting DNA at specific sites, restriction endonucleases create "sticky ends" or "blunt ends" that can be joined with other DNA fragments. This enables the insertion of foreign DNA into a vector, facilitating the creation of recombinant DNA molecules.
| 3. How do restriction endonucleases recognize specific DNA sequences? | |
Ans. Restriction endonucleases have the ability to recognize and bind to specific DNA sequences, known as recognition sites or restriction sites. These recognition sites are usually palindromic, meaning they read the same on both strands of DNA. The enzyme scans the DNA molecule until it finds its specific recognition site, where it then cleaves the DNA.
| 4. Are all restriction endonucleases the same? | |
Ans. No, restriction endonucleases are not all the same. They are classified into different types based on their recognition sequences and cleavage patterns. For example, Type II restriction endonucleases are the most commonly used and recognize specific palindromic sequences, while Type I and Type III restriction endonucleases have more complex recognition and cleavage mechanisms.
| 5. Can restriction endonucleases be used in forensic analysis? | |
Ans. Yes, restriction endonucleases can be used in forensic analysis. By cutting DNA at specific recognition sites, restriction endonucleases can generate unique DNA fragment patterns, known as restriction fragment length polymorphisms (RFLPs). These RFLPs can be used to analyze DNA samples, such as in paternity testing or criminal investigations, where the patterns can be compared to identify individuals or establish relationships.
