Later it was found that the sugar in nucleic acid can be ribose or deoxyribose ... Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked.

Nucleotides also play crucial roles in various cellular processes, including energy transfer and enzymatic reactions. The structure of a nucleotide, consisting of a phosphate group (left), a pentose ...

Each ribonucleotide base consists of a ribose sugar, a phosphate group ... Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
