免疫防御机制演化出许多不同策略，原核生物运用核酸的限制内切酶、抗微生物胜肽及RNA干扰素作为自我防卫。
The evolution of mechanisms for immune defense has resulted in a variety of strategies. Prokaryotes use restriction endonucleases, antimicrobial peptides, and RNA interference for self-protection.
锌指核酸酶是一种人工制做限制性内切酶，通过将锌指DNA结合区与限制性内切酶的DNA切割区融合获得。
Zinc finger nucleases (ZFNs) are artificial restriction enzymes made by fusing an engineered zinc finger DNA-binding domain to the DNA cleavage domain of a restriction enzyme.
方法：用甲基化敏感的限制性核酸内切酶消化，结合聚合酶链反应（PCR）技术。
Methods: 20 cases of MDS patients were studied using methylation sensitive restriction enzyme digestion and polymerase chain reaction(PCR) technique.
