GAATTC is the restriction sequence of

• Explanation:
-The DNA sequence GAATTC is indeed the specific recognition sequence for the restriction enzyme Eco RI. This enzyme cuts DNA at this palindromic sequence, creating sticky ends that are useful in DNA cloning and recombinant DNA technology.

📌 Other Options Explanations:
-(b) Bam HI: Bam HI recognizes the sequence GGATCC.
-(c) Sau 3: Sau 3 recognizes the sequence GATC
-(d) Nco I: Nco I recognizes the sequence CCATGG.
Each restriction enzyme has its own unique recognition sequence, making them valuable tools for precise DNA manipulation.
