BIOCHEM 2280- FINAL EXAM QUESTIONS AND ANSWERS LATEST 2025/2026 UPDATE 100% ACCURATE what is a nucleoside, what are the components to it, and how are the carbons numbered --this is when there is a sugar and a nitrogenous based attached to each other -the N that is added to a ribose sugar is labelled 1, then the C and N in the ring are labelled going counter clockwise so N1 is connected to 1' of the ribose sugar with a N-glycosidic bond -this bond is connected to the anomeric carbon to, the sugar can no longer switch between alpha and beta, al sugars in RNA and DNA are in beta configuration -so C connected to base is called 1' then label carbon going clockwise, put a prine (') on the number -if the base is cytosine, then the whole molecule w the sugar and base is called cytidine, this is the ribonucleoside
