Q: What is the role of restriction enzymes in molecular biology?
Solution:
Restriction enzymes cut DNA at specific sequences, which is essential for cloning and recombinant DNA technology.
Steps: 6
Show Steps
Step 1: Understand that DNA is made up of sequences of nucleotides.
Step 2: Learn that restriction enzymes are special proteins that can cut DNA.
Step 3: Know that each restriction enzyme cuts DNA at a specific sequence of nucleotides.
Step 4: Realize that cutting DNA is important for scientists to manipulate genes.
Step 5: Understand that this cutting process is used in cloning, which means making copies of DNA.
Step 6: Recognize that it is also used in recombinant DNA technology, where DNA from different sources is combined.
