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.

By tagging each DNA or RNA molecule and allowing neighboring tags to interact, the technique constructs a molecular network that encodes their relative positions, creating a spatial map of genetic ...

Let's take a look at how to observe cells under a microscope. No prizes for guessing the first thing you'll need: a microscope. But don't worry if you don't have one of your own. Ask your school ...

When scientists isolated the kinetoplast using density gradients and centrifugation, collected the DNA content on grids, and studied it under the electron microscope, they discovered that the kDNA ...

First, as observed, DNA forms overlapping loops—first ... see in the shape the genome takes in interphase and mitosis under the microscope." ...

“To be able to see that kind of a view of nature from within a specimen is exhilarating.” DNA microscope creates 3D images of organisms from the inside out. (Image: Weinstein Lab, University of ...
