What are restriction enzymes and their significance in recombinant DNA technology?
Understand the Problem
The question is discussing the concept of restriction enzymes in recombinant DNA technology, particularly focusing on their discovery and function in isolating specific DNA sequences.
Answer
Restriction enzymes cut DNA at specific sites, crucial for recombinant DNA technology.
Restriction enzymes are proteins that cut DNA at specific sequences, creating fragments with defined ends. They are vital in recombinant DNA technology for gene cloning, genome mapping, and DNA modification. They allow for the precise manipulation of DNA for genetic engineering purposes.
