The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's ...

In Lewis Carroll's "Through the Looking-Glass," Alice is stuck in a never-ending race with the Red Queen yet never gains a lead. "It takes all the running you can do to keep in the same place," the ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

“Our lab is generally interested in discovering and characterizing previously unknown or poorly understood factors that are essential for genome maintenance. This is particularly important in the ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

In this first instalment of Radio Prague International’s brand new edition of Science without Borders, Štěpánka Nedvědová sheds light on the work of a molecular scientist.

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein synthesis right at the start. An international research team with significant ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
