Left-handed Z-RNA and Right-Handed A-RNA

Caption

The front ribbon of the Z-RNA Double-Helix points upwards to the left. In A-RNA and in Watson-Crick B-DNA the foremost ribbon points upwards to the right. Left handed Z-RNA can form from right-handed A-RNA by flipping the steps of the double helix upside down. The steps can be flipped by holding, then twisting each end of the helix
