Given the antiparallel orientation of the two strands that make up duplex DNA, it is reasonable to expect that some helicases unwind DNA in a 5′→3′ direction, while others unwind DNA in a 3 ...

A particularly dangerous type of DNA damage is called a double-strand break, in which the two antiparallel strands of the DNA double helix break in the same place, making it difficult for a cell to ...

It may be why life is screwed up A tightrope of DNA between two silicon nanopillars It's the most famous corkscrew in history. Now an electron microscope has captured the famous Watson-Crick ...

Credit: Cell (2024). DOI: 10.1016/j.cell.2024.07.034 Researchers have developed a tool that can bend DNA strands using light. The work represents a new way to probe the genome.

Just like twins recognising and approaching each other across a crowded room, it now turns out that identical stretches of double-stranded DNA seek each other out in solution. The unexpected ...

Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have used microscopic strands of DNA to guide the assembly of gel blocks that are visible to the naked eye.

After DNA damage, for example by chemicals, the damaged and undamaged DNA strands are separated from each other during cell division. The cells often do not repair the DNA damage immediately; the ...

Researchers have developed a tool that can bend DNA strands using light. The work represents a new way to probe the genome. Shown here, from an unrelated study, are chromosomes (blue) inside a ...
