A research team has discovered that accumulated DNA damage in the retina is a key contributor to age-related macular degeneration and that targeting specific retinal cell types may lead to treatments ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

DNA polymerases are the “Xerox machines” that replicate our DNA. They must work with great precision to keep errors from creeping into our genes. In spite of this precision, they still accept building ...

Researchers have identified DNA from a virus that circulates widely in farmed shrimp and shellfish inside the eye tissues of patients suffering from a chronic, pressure-related inflammatory eye ...
