Quizplus · Accepted Answer

The most accurate design suggestion for a spiral staircase representing DNA would be for people climbing the staircase to step on pairs of bases. This accurately represents the structure of DNA, where two complementary nitrogenous bases form a base pair held together by hydrogen bonds. The other design suggestions, such as painting the steps to look like phosphates and sugars or using handrails made of sugars, do not accurately represent the structure of DNA and may confuse visitors to the museum. The support post running down the center could be an optional design feature, but it is not necessary for scientific accuracy.
