Researchers have discovered how the protein XPD detects severe DNA damage and controls its repair. The XPD protein is a central component of our body's own "DNA repair team," known as nucleotide ...

which is more compact than normal DNA. Using cryo-electron microscopy (cryo-EM), a team of structural and molecular ...

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 ...

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.

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 ...

There's three types of microscope: light, like this one here, and two types of electron microscopes, like those ones over there. Light microscopes use light and mirrors and can see things as small ...

The limit of resolution of the transmission electron microscope is now less than 1 nm. The TEM has revealed structures in cells that are not visible with the light microscope.
