(Remember, DNA is almost always in a double-stranded helical form.) Furthermore, RNA contains ribose sugar molecules, which are slightly different than the deoxyribosemolecules found in DNA.

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality ...

Adenine and guanine, the two most common purines in DNA and RNA, share this core structure ... It consists of an adenine base, a ribose sugar, and three phosphate groups. The hydrolysis of ATP ...
