NEET Biology question

**Statement 1:** A bacterial cell with no restriction enzymes will be easily infected and lysed by bacteriophages. **Statement 2:** Restriction enzymes catalyze the synthesis of a protective coat around the bacterial cell that prevents bacteriophage attack.

(A)Both statements are true and Statement 2 is the correct explanation of Statement 1
