These eight random poly(AC) RNAs produced proteins containing only six amino acids: asparagine, glutamine, histidine, lysine, proline, and threonine. Remember that previous experiments had already ...

Amino acids are small molecules that are the building blocks of proteins. Proteins serve as structural support inside the cell and they perform many vital chemical reactions. Each protein is a ...

Nine of the amino acids that people need for making protein ... An example of a structural protein is actin. Transport and storage proteins attach themselves to atoms and small molecules ...

Key molecules in animals' bodies like enzymes and hormones are actually just specialized proteins, and other proteins like ...

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 ...
