Unlike traditional microscopes that use light or lenses, DNA microscopy creates images by calculating interactions among molecules, providing a new way to visualize genetic material in 3D.

This study shows that “one can use a very simple imaging device such as the mobile phone to record DNA sequencing reactions,” said coauthor Mats Nilsson of Stockholm University in Sweden. The ...

The trunk of each 'Christmas tree' (a transcription unit) represents a DNA molecule; the tree branches (granular strings attached to the DNA) are RNA molecules that have been transcribed from the DNA.
