In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Those 'DNA knots' weren't knots at all, and the truth is stranger
For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...
The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...
Before Watson and Crick basked in Nobel glory, before The Double Helix mythologized their genius, there was the photo. Photo 51 — crisp, clear, and groundbreaking — captured by Dr. Rosalind Franklin, ...
Using advanced imaging techniques and precise microfluidics control to stretch out curly DNA into a straight line, new research demonstrates techniques for stretching and immobilizing DNA with minimum ...
