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.

At different times during the life cycle of a cell, the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more ...

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 ...

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

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 ...

“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 ...
