The Summit supercomputer revealed how damaged strands of DNA are surgically repaired by a molecular pathway called nucleotide excision repair, or NER. NER’s protein components can change shape to ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

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 ...

Since the first reported cases in 1981, the human immunodeficiency virus (HIV) infected approximately 86 million people and resulted in the deaths of tens of millions of people from acquired ...
