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 ...

Molecular Intelligence’s end users are research ... But, Kihara said, cryo-EM’s low-resolution image data means building structure models of proteins, nucleic acids and drug molecules is not trivial. ...

The researchers were examining how the 3D organization of the genome controls development and needed to image ... RNA and proteins are organized in tissues. The team also automated the system, ...

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 ...

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.

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 ...

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 ...

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 ...
