The correct Answer is:
### Step-by-Step Solution: 1. **Understanding EcoRI**: EcoRI is a restriction endonuclease enzyme derived from the bacterium *Escherichia coli*. The name EcoRI indicates that it is from *E. coli* (Eco) and is the first enzyme (R) isolated from a specific strain (I). 2. **Function of EcoRI**: This enzyme is known for its ability to cleave DNA at specific sequences. It recognizes a particular palindromic DNA sequence and cuts the DNA strands. 3. **Type of Ends Produced**: When EcoRI cleaves the DNA, it does not produce blunt ends (which are straight cuts). Instead, it creates sticky ends. Sticky ends are produced when the cuts are made in such a way that they leave overhanging nucleotides at the ends of the DNA fragments. 4. **Characteristics of Sticky Ends**: The overhanging ends created by EcoRI are referred to as sticky ends because they can easily anneal (bond) with complementary DNA strands, facilitating the process of DNA recombination. 5. **Conclusion**: Based on the above points, the correct answer to the question "EcoRI cleaves DNA strands to produce" is "sticky ends". ### Final Answer: EcoRI cleaves DNA strands to produce **sticky ends**. ---
