In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by ...

University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. A University of Iowa-led study ...

Scientists have for the first time looked deep into the protein structure that may determine our vision - and discovered that ...

Proteins are fundamental biomolecules that perform a broad range of vital functions within the human body. They serve as an essential structural and functional component of cells, tissues and organs ...

Why is knowing the atomic structure of molecules useful? Learn why, and how information like this about protein structure is shared through a publicly available database. Scientists use a variety ...

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 ...
