DNA replication is a complicated affair: Proteins must identify where on DNA to start replicating, unwind the double helix, synthesize a primer, and then elongate the DNA strand from the end of that ...

In the early 1990s, Jacqueline Barton, the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry at Caltech, discovered an unexpected property of DNA--that it can act like an electrical wire to ...

Undergraduate biology students could be forgiven for thinking that scientists have DNA replication all figured out. After all, textbooks present the models of replication so matter-of-factly that it's ...

The cellular replicative DNA polymerases cannot initiate DNA synthesis without a priming 3′ OH. During DNA replication, this is supplied in the context of a short RNA primer molecule synthesized by ...

For all species, the process of DNA replication requires the use of multiple different DNA polymerase enzymes. The primary function of these unique multisubunit enzymes is to ensure optimal DNA ...
