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 ...

This article was originally published with the title “ The Three-Dimensional Structure of a Protein Molecule ” in Scientific American Magazine Vol. 205 No. 6 (December 1961), p. 96 doi:10.1038 ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

Single-molecule imaging, a technique that uses fluorescent markers to track proteins with precision, plays a crucial role in cell biology, biochemistry, molecular biology, and drug discovery.

One our aims is the molecular analysis and imaging of peptides and proteins in brain tumors ... froze them using liquid nitrogen. For image analysis, we cut the tumor tissue using a microtome ...

How does the cell convert DNA into working proteins? The process of translation ... not all regions of an mRNA molecule correspond to particular amino acids. In particular, there is an area ...
