Question

Restriction endonucleases recognize specific sequences and perform:

RankGuru · Accepted Answer

1. **Identity**: Restriction endonucleases are known as 'molecular scissors'.
2. **Recognition**: Each restriction enzyme inspects the length of a DNA sequence until it finds its specific **recognition sequence** (usually a palindromic sequence).
3. **Function**: Once found, it binds to the DNA and cuts (cleaves) each of the two strands of the double helix at specific points in their sugar-phosphate backbones.
4. **Role**: This property is essential for creating recombinant DNA molecules by cutting different DNA sources with the same enzyme to produce matching 'sticky ends'.
