Q: What is the purpose of using restriction enzymes in molecular biology?
Solution: Restriction enzymes cut DNA at specific sequences, allowing for the manipulation and cloning of DNA fragments.
Steps: 6
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 at specific locations.
Step 3: Know that these specific locations are called 'restriction sites' and are usually short sequences of nucleotides.
Step 4: Realize that by cutting DNA, scientists can isolate specific pieces of DNA they want to study or use.
Step 5: Understand that this process is important for cloning, which means making copies of DNA fragments.
Step 6: Recognize that manipulating DNA with restriction enzymes helps in various applications like genetic engineering, creating recombinant DNA, and studying genes.
