iPOND Method Goes Fishing for Proteins

Friday, March 16th, 2012

Understanding DNA replication and DNA damage responses – which must proceed faithfully to prevent diseases such as cancer – requires the ability to monitor protein dynamics at active and damaged replication forks (sites of DNA duplication). Existing methods for studying replication fork machinery have been limited in resolution and sensitivity. Now, David Cortez, Ph.D., and […]

DNA Mechanics

Wednesday, December 8th, 2010

Picture a railroad track, running across the countryside. DNA looks something like that track. Its “rails” are chains of chemicals called nucleotides, each pairing with a partner on the opposite chain to form the “ties.” To ensure timely train traffic – and prevent catastrophic derailments – the railroad track needs regular maintenance. So does DNA. […]
