Question

What are the basic building blocks of DNA and RNA?

Answer 1

Building Blocks of DNA /RNA
(DeoxyriboNucleaic Acid and RiboNucleaic Acid)

The sugar part of DNA is deoxyribose which is very closely related to ribose which is itself similar to glucose. These three molecules are in the Moilin Library under bio_molecules.
You can use Moilin to examine a-d-glucose

Answer 2

RNA Building Blocks. ​Every strand of RNA is a sequence of four building blocks called nucleotides. ... The sugar and phosphate groups form the backbone of a strand of RNA, and the bases bond to each other. RNA nucleotides contain a sugar called ribose, whereas DNA nucleotides contain a sugar called deoxyribose.
