مکانیسمی که به تازگی کشف شده است به سلول ها کمک می کند تا از خطا در حین تکثیر DNA جلوگیری کنند

A newly discovered mechanism helps cells prevent errors during DNA replication

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart muscle cells divide far less frequently. All of this depends on the molecular machinery responsible for copying the billions of chemical units that make up DNA inside the nucleus.
