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.

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

A single DNA nucleotide, the base unit of the human ... it much too small to be identified by even the most powerful electron microscope. So how, then, do researchers determine the sequence ...

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 ...

Scanning Transmission Electron Microscopy (STEM) and Transmission Electron Microscopy (TEM) are two closely related imaging techniques used in material science, nanotechnology, and biology for ...

One of the main challenges of contemporary medicine is posed by the resistance of pathogens to antibiotics. An important step ...

The Electron and Scanning Probe Microscopy Unit provides solutions for imaging and analysis at the nanoscale. The unit houses two scanning electron microscopes, two scanning probe microscopes and ...

When all you’ve got is a hammer, everything looks like a nail. And when you’ve got a scanning electron microscope, everything must look like a sample that would be really, really interesting ...
