Under the electron microscope, DNA molecules undergoing transcription exhibit Christmas-tree-like structures.
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.
