Aldopentoses named as ribose and 2-deoxyribose are found in nucleic acids. What is their relative configuration?

Aldopentoses like ribose and 2-deoxyribose are the sugar moieties in nucleic acids like RNA and DNA respectively. The structures of these sugars are given below. The configuration of both the aldopentoses is D-configuration. Ribose is named β-D-ribose and 2-deoxyribose is β-D-2-deoxyribose.
