WebLeft hands make up over 90% of the artwork, demonstrating the prevalence of right-handedness [1] In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more dextrous. The other hand, comparatively often the weaker, less dextrous or simply less subjectively ...

WebSolution. Portions of proteins can arrange in regularly repeating structures such as α-helices: the vast majority of these helices are right-handed (the left-handed versions are very rare). Similarly, DNA (double) helices can arrange into right-handed (A-DNA and B-DNA) or left-handed (Z-DNA) helices. If you have a helix in front of you ... WebOct 10, 2000 · WP900 binds to DNA with unique structural selectivity and strongly prefers left-handed DNA to the normal right-handed B-form, in contrast to daunorubicin, for which the pattern of selectivity is reversed. Molecular dynamics simulations show that intercalation into left-handed Z-DNA represents a plausible mode of WP900 binding.
