Until now. Two laboratories recently used cryo-electron microscopy to directly image atoms in a protein molecule with a resolution of about 1.2 x 10-7 millimeters or 1.2 ångströms. The previous ...

Ribosomes are the cell’s molecular machines ... isolated RQCs from yeast cells and used cryo-electron microscopy to develop three-dimensional images of their interactions with large ribosomal subunits ...
