I am bit confused about restriction enzymes and how they recognize to perform their function.
Situation 1) A bacteria cell is infected by a bacteriophage, which injected some viral progeny into it. Restriction enzymes recognize the viral DNA due to its unmethylated palindromic sequence. Once recognized, the viral DNA is somehow degraded. The restriction enzymes don't "attack" the bacterial DNA since it is methylated. [concept learned: the mechanism for bacterias to eliminate foreign...
