Inspection of the double-ladder pattern of topoisomers derived from a randomly cyclized trefoil (Fig. 2 , lanes 1 and 2) suggests that the intensities of each pair of bands in a doublet are about the same; this equality is confirmed by the densitometric tracing of the distribution (Fig. 7 a ). read english aloud

Simulated and experimental depth-resolved … WebOct 28, 2024 · The idea that we also test is that in the case of chiral superstructures such as polymer knots, the helical channels do not have to be carved so perfectly because the chiral superstructures represented by polymer knots are soft and flexible; hence, they can adjust to dimensions of the channel. 2. Materials and Methods 2.1. Model of DNA Chain In mathematics, a figure is chiral (and said to have chirality) if it cannot be mapped to its mirror image by rotations and translations alone. For example, a right shoe is different from a left shoe, and clockwise is different from anticlockwise. See for a full mathematical definition. A chiral object and its mirror image are said to be enantiomorphs. The word e… read end of file linux
