The orange wheel shows the circular chromosome or genome of E. coli bacteria. The spikes indicate where a molecular intermediate in DNA repair -- four-way DNA junctions -- accumulate near a reparable ...
a | Electron-microscope image of a recombination intermediate. In this image, the Holliday junction was partially denatured to assist its visualization. b | Two possible configurations for the ...
Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form ...
