(biochemistry) a nucleoside that is a structural component of nucleic acids; it is present in all living cells in a combined form as a constituent of DNA and RNA and ADP and ATP and AMP
"The scientist explained how adenosine serves as the fundamental building block within both DNA and RNA molecules, forming the backbone that stores genetic information in every cell."
