Which carbon atom of deoxyribose sugar in DNA does not contain
1 \(\mathrm{\mathrm{C}_{5}}\)
2 \(\mathrm{\mathrm{C}_{3}}\)
3 \(\mathrm{\mathrm{C}_{2}}\)
4 \(\mathrm{\mathrm{C}_{1}}\)
Explanation:
Deoxyribose is a pentose sugar with five carbon atoms. The four carbon atoms of the ring are numbered \(\mathrm{1^{\prime}, 2^{\prime}, 3^{\prime}}\) and \(\mathrm{4^{\prime}}\). The carbon atom of \(\mathrm{-\mathrm{CH}_{2} \mathrm{OH}}\) is numbered \(\mathrm{5^{\prime}}\). There are three -OH groups at position \(\mathrm{1^{\prime}, 3^{\prime}}\) and \(\mathrm{5^{\prime}}\). Hydrogen atoms are attached to carbon atoms \(\mathrm{1^{\prime}, 2^{\prime}, 3^{\prime}, 4^{\prime}}\) and \(\mathrm{5^{\prime}}\). Only carbon atom at \(\mathrm{\mathrm{C}_{2}}\) of deoxyribose sugar in DNA does not contain -C OH bond. Note The prefix \(\mathrm{2^{\prime}}\) - deoxy means that oxygen is missing from the \(\mathrm{2^{\prime}}\) position of ribose.
