Most cells in the human body each contain about six feet of DNA. Yet the nucleus, where DNA is coiled, is no larger than a ...

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

Thus, the 30-nanometer fiber may be highly irregular and not quite the uniform structure depicted ... that unwind and copy DNA. It is therefore important for cells to have means of opening up ...

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 ...

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 ...

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 ...

A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they divide, a key process in keeping cells healthy.

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 ...
