Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction ...

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

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes ... The DNA is wrapped around histones -- protein structures that are sometimes ...

The graphic shows images of a cell under mtDNA replication stress made using so-called Correlative Light and Electron Microscopy (for short: CLEM). The mitochondrial DNA (mtDNA, green) is ejected ...

Each of us has enough DNA to reach from here to ... opening up chromatin fibers and/or removing histones transiently to permit transcription and replication to proceed. Generally speaking, there ...

The team thought it might be a good candidate for finding histones because the bacterium changes size throughout its lifecycle and thus would need to carefully time DNA compression and unwinding. As a ...
