is made of right-handed chiral molecules which combine to form a right-handed double helix. The left-handed version would look like its mirror image, forming a helix that spins in the opposite ...

The left-handed Z ... pairs within some right-handed DNA molecules. The site where the DNA molecule switches chirality is called a B-Z junction. At this point in the polymer, one A-T base pair ...

This dominance is demonstrated in the way the double helix of a DNA strand presents itself - if you could climb it you'd find yourself always turning right. Why DNA has a right-handed bias has ...

The control of artificial double ... handed or M-form, and in Lewis basic solvents (acetone, DMSO), it becomes right-handed or the P-form. The conformation of chiral chains introduced into the ...

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 Advanced Search ...

The familiar Watson-Crick double helix of DNA, called B-DNA, winds in a right-handed direction. But like a screw, the helix can wind the other way: under certain conditions, DNA adopts a left ...

The double helix is a description of the molecular shape of a double-stranded DNA molecule.
