What is the role of restriction enzymes in molecular biology?
Correct Answer: Restriction enzymes cut DNA at specific sequences.
- 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.
