Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Among today's rapidly growing fields of biological study are those focusing on neurotransmitters, hormones, and various immunological and pharmacological agents. Central in many of these ...
