1) a) Sketch an A-form helix and a B-form helix, highlighting the differences between them. Indicate the bases and backbone as lines. Label the major and minor grooves. 2) Sketch a ribose in the pucker that is expected in RNA. 3) Sketch a 2’ deoxyribose in the pucker that is expected in DNA. 4) Draw a GCG triplet (GC Watson-Crick), with perfect geometry. Draw the bases only, with dR’s at the N-9 positions of the purines (Gs) and at the N1 positions of the pyrimidine (C)
