Although characteristics vary under the laws of different countries, it can be described as: 1  a privileged claim, 2  upon maritime property, 3  for service to it or damage done by it, 4  accruing from the moment that the claim attaches, 5  travelling with the property unconditionally, 6  enforced by an action in rem.
Visualization: ethidium bromide (EtBr) and dyes The most common dye used to make DNA or RNA bands visible for agarose gel electrophoresis is ethidium bromide, usually abbreviated as EtBr. It fluoresces under UV light when intercalated into DNA (or RNA).
Ethidium bromide is an intercalcating dye, which means it inserts itself between the bases that are stacked in the center of the DNA helix. One ethidium bromide molecule binds to one base. As each dye molecule binds to the bases the helix is unwound to accommodate the strain from the dye.Closed circular DNA is constrained and cannot withstand as much twisting strain as can linear DNA, so circular DNA cannot bind as much dye as can linear DNA.ne ethidium bromide molecule binds to one base.
