...The researchers then changed the appearance of the traps to test whether the rooks actually understood the task. For example, in one task the non-functioning trap was bottomless, allowing food to fall through. In a so-called transfer test, the food could pass over the top.

However, each base in the DNA ladder--A, T, G or C--is only separated by about 3.4 angstroms.
