Each protein is a molecule made up of different combinations of 20 types of smaller, simpler amino acids. Protein molecules are long chains of amino acids that are folded into a three-dimensional ...

Proteins are the workhorses that keep our cells running, and there are many thousands of types of proteins in our cells, each performing a specialized function. Researchers have long known that the ...

An artificial intelligence model has created a new protein that researchers say would have taken 500 million years to evolve ...

The photograph shows a model of lysozyme a hanging from the ceiling with its 129 amino acids in an extended conformation. Constructed from components on a scale of 2 cm to the Ångstrom ...

The model has uncovered a hidden layer of molecular code that shapes biological organization, adding new dimensions of ...

Each codon specifies a particular amino acid or a stop signal. The genetic code is nearly universal across all living organisms, with only minor variations in some species. DNA mutations are changes ...
