Adenosine, is one of the nucleotides used to build RNA. It is also incorporated into DNA, but in DNA the ribose ring is a 2'-deoxyribose ring. In both DNA and RNA, adenosine is linked to the other nucleotides by phosphodiester bonds at both the 3'- and 5'- positions. In duplex DNA, the adenine base present in adenosine is hydrogen bonded with, that is, it forms a base pair with, a thymidine nucleotide on the opposite DNA strand.
