DNA polymerases are proteins that synthesize new DNA strands using preexisting DNA strands as templates. Before one cell divides to produce two cells, the DNA containing the genetic information in it must be duplicated for the new cell, in a process...

A DNA polymerase is an enzyme that assists in DNA replication. Such enzymes catalyze the polymerization of deoxyribonucleotides alongside a DNA strand, which they "read" and use as a template. The newly-polymerized molecule is complementary to the...

The primary role of DNA polymerases is to accurately and efficiently replicate the genome to ensure the maintenance of the genetic information and its faithful transmission through generations. This is not a simple task considering the size of the genome and its constant exposure...

In a recent collaborative study, Thomas A. Kunkel, director of the NIEHS Environmental Biology Program, NIEHS deputy director Samuel H. Wilson, and Roger Woodgate, an investigator at the National Institute of Child Health and Human Development, report novel findings about DNA repair and...
