Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could affect how certain cancer drugs are developed. Published in Genes & Development, the study shows how ATR helps stabilize the cell's DNA-copying machinery during replication stalls, preventing chromosomes from breaking.
