The observation by electron microscopists ... To accomplish this, the DNA becomes highly compacted into the classic metaphase chromosomes that can be seen with a light microscope.

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.
