A DNA molecule that resembles a spiral staircase is called a double helix. The double helix is formed as a consequence of its secondary structure. This is an important component in helping determine its tertiary structure.
b. double helix (just took the test)
A DNA molecule has a unique design that resembles a spiral staircase that scientist call a double helix. It is a winding, two stranded chemical structure.

It's a dual-helaxiocase.
a (double) helix.
If the spiral molecule is DNA then the four bases are Adenine, Thymine, Cytosine and Guanine.
A grand design spiral galaxy (like Whirlpool Galaxy) has prominent and well defined spiral arms, whereas a flocculent galaxy (like Sunflower Galaxy) has short segments of spiral structure, "fluffy" in appearance, but without the dramatic well defined spiral arms of a grand design spiral.
