A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

Kanazawa University and colleagues have achieved a breakthrough in understanding sperm DNA packaging. Using high-speed atomic ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

Beckwith and colleagues used a method to gently remove one strand of DNA in cells at various stages of cell division, keeping the chromosome structure intact. They could then use targeted sets of ...

which is based on the idea that genetic information -- the blueprint for the cell structure, for example -- is translated using self-folding RNA alone. First, a DNA sequence is designed in a ...

The DNA of human cells consists of a sequence of about 3.1 billion building blocks. Cells go to great lengths to maintain the integrity of this vast store of information. They constantly untangle ...

Scientists at the University of Iowa have made an exciting discovery that could lead to new cancer-fighting drugs. They found ...

RAD52 has already shown promise as a drug target. Inhibitors of the protein can selectively kill cancerous cells while sparing healthy ones, reducing the collateral damage typically caused by ...

And yet, the DNA was everywhere ... in the nucleus" of the surrounding cell, says Coale. But in this case, the process led to the nitroplast, and the structure is responsible for pumping ...

A comprehensive review titled "From the Test Tube to the Cell: A Homecoming for DNA Computing Circuits?" published Mar. 4 in ...
