Though it is significantly less colorful than textbook DNA, and a tad less tidy than the double ... an electron microscope. Yes. YES. And here's an even-closer-up view of the strand itself ...

But the integrity of double-stranded DNA depends on both the stacking forces ... the Duke team used an atomic force microscope (AFM) to capture the "mechanical fingerprint" of the attraction ...

Scientists have seen individual double-stranded DNA molecules under optical microscopes for years, but the ability to see single-stranded DNA is a new achievement, and breaking the diffraction ...

The DNA in our cells spends most of its time in the familiar double helix structure ... By looking at a strand of DNA under a special microscope, the researchers were able to see whether an ...
