The correct Answer is:
To answer the question, we need to identify the specific base sequence that Hind-II recognizes in DNA. Here’s a step-by-step breakdown of the solution: ### Step 1: Understanding Restriction Enzymes Restriction enzymes, also known as restriction endonucleases, are proteins that cut DNA at specific sequences. Each restriction enzyme recognizes a unique sequence of nucleotides. **Hint:** Think about the role of restriction enzymes in molecular biology and how they interact with DNA. ### Step 2: Recognizing the Specific Sequence Hind-II recognizes a specific sequence of six base pairs in the DNA. This sequence is crucial for the enzyme's ability to bind and cleave the DNA. **Hint:** Consider what the term "specific sequence" implies in the context of DNA and restriction enzymes. ### Step 3: Defining the Sequence The specific base sequence recognized by Hind-II is referred to as the "recognition site" or "restriction site." This is the location where the enzyme will cut the DNA. **Hint:** Recall the terminology used in genetics and molecular biology to describe where enzymes interact with DNA. ### Step 4: Conclusion Thus, the specific base sequence recognized by Hind-II is known as the **recognition sequence** or **restriction site**. **Final Answer:** The specific base sequence is known as the **recognition sequence** or **restriction site**. ---
