Plant polymerases IV and V are special forms of Polymerase II
It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic... view more...

New gene silencing pathway found in plants
Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes. view more (2008-11-18)
Little known DNA repair enzyme may be a tumor suppressor gene
The DNA in our cells is constantly being bombarded by environmental, chemical and cellular insults. Fortunately, our cells contain many enzymes devoted strictly to detecting and repairing any damage caused by these insults. view more (2006-01-04)
Molecular typesetting -- proofreading without a proofreader
Researchers at the Universities of Leeds and Bristol (UK) have developed a model of how errors are corrected whilst proteins are being built. view more (2009-06-23)
Common Enzyme is a Key Player in DNA Repair
A quarter century after they discovered it, researchers have identified the job of one of the most common DNA-damage response proteins. view more (2006-01-12)
Properties of Unusual Virus Revealed in Researchers
A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell. The results, which are published in the current issue of the journal Molecular Cell, contribute... view more... (2008-12-09)
Stopgap DNA Repair Needs a Second Step
One can have a dream, two can make that dream so real, goes a popular song. Now a Weizmann Institute study has revealed that it takes two to perform an essential form of DNA repair. view more (2009-05-04)
Enzyme alerts cell's powerful army to repair DNA damage
Scientists know that inside each cell, a little engine called RNA polymerase II does one essential job: It copies instructions from genes in the nucleus that get carried to production units in the rest of the cell to support our daily needs. view more (2007-09-06)
Hepatitis C helicase unwinds DNA in a spring-loaded, 3-step process
The process by which genes are duplicated is mysterious and complex, involving a cast of characters with diverse talents and the ability to play well with others in extremely close quarters. view more (2007-07-27)
MIT, BU engineer cellular circuits that count events
MIT and Boston University engineers have designed cells that can count and "remember" cellular events, using simple circuits in which a series of genes are activated in a specific order. view more (2009-05-29)
Hepatitis B drug can compromise HIV treatment
Treating hepatitis B patients with the drug entecavir can cause those who are also infected with HIV to become resistant to two of the most important drugs in the anti-HIV arsenal. view more (2007-06-21)
