Questions & Step-by-Step Solutions
What is the significance of the 'sticky ends' produced by restriction enzymes? (2023)
Step 1: Understand what restriction enzymes are. They are proteins that cut DNA at specific sequences.
Step 2: Learn what 'sticky ends' are. When restriction enzymes cut DNA, they can leave overhanging ends, which are called sticky ends.
Step 3: Know why sticky ends are important. These overhanging ends can easily pair with complementary sequences of DNA.
Step 4: Realize how this helps in DNA manipulation. When you want to join two pieces of DNA together, sticky ends make it easier because they can stick to each other.
Step 5: Understand the process of ligation. After the sticky ends pair up, an enzyme called ligase can join them permanently, creating a new DNA molecule.
