Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

From proofreading polymerases to complex backup repair systems, DNA repair is a high-yield MCAT topic that bridges molecular biology and human health. Understanding the mechanisms that safeguard ...
