Abstract
Telomeres are nucleoprotein structures that shelter the ends of linear chromosomes from being inappropriately recognized as DNA double-strand breaks. New work has revealed that Apollo, a nuclease previously implicated in DNA repair, also has a role in safeguarding telomeres during S phase.
摘要
端粒是一种核蛋白结构，可保护线性染色体的末端不被错误地识别为DNA双链断裂。新的研究表明，Apollo（一种先前与DNA修复有关的核酸酶）在S期保护端粒方面也发挥着作用。
