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.

An atomic force microscope uses a cantilever with a sharp ... and it prevents the molecule [under study] from being bonded to the tip,” explains Leo Gross, a scientist on the IBM Research ...

Caption This is an illustration of a buckydiamondoid molecule under a scanning tunneling microscope (STM). The sharp metallic tip of the STM ends in a single atom; as it scans over a sample ...

They vary in size, but are extremely small. You can’t see an individual molecule with your eyes or even a microscope. They are 100,000 times smaller than the width of a hair. The smallest molecule is ...

This causes the molecules in the sample to move apart evenly and also become larger, so that they can be imaged with a light microscope ... images of the entire molecule are available less than ...
