hmm...I thought so too remer, but didn't like to to say so! (corkscrews)..there are LH and RH ones as well. (I KNEW too helices was the plural of helix)!

Its surreal to get a close up look at what makes you you.

No, they don't, but nice note. In solution alternating purine-pyrimidine residues assume the left-handed conformation only in the presence of high concentrations of positively charged ions (for example, Na+) that shield the negatively charged phosphate groups. At lower salt concentrations, they form typical right-handed conformations. The physiological significance of Z DNA is uncertain and left-handed helices probably account at most for only a small proportion of a cell's DNA.

DNA helixes ALWAYS twist to the right, like a corkscrew. This has been flipped left to right.

I like it.
