Problem 5: Is the deoxyribose ring flat or puckered?

Do all the atoms of the sugar ring lie in the same plane? (Note: You can measure this directly by clicking on 4 consecutive ring atoms with the dihedral angle tool at the far right of the tool bar. If the ring is planar, the measured angle will be close to either 0 or 180 degrees).

A. yes
B. no, the ring is puckered
