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 ...

have studied the role of a specific protein, gamma-actin, in the organization and mechanics of epithelial cells and their junctions. Their work, published in Nature Communications, reveals a ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.
