You are probably thinking of DNA. The base pairs link the two strands together like a series of steps. However, since it is helical, it might be more accurate to compare it to a spiral staircase.
Two strands of DNA intertwined together and twisted to form a double helix. The sugar phosporous backbone is like the side of the stairs and the nucleotide bases are like the steps of the stairs.
3 steps: First, the Glycolysis Second, the Pyruvic acid oxidation Third, the Krebs Cycle
The thirty-nine steps are located on the Ruff, near Bradgate. There are several sets of stairs- thirty-four, thirty-five, thirty-nine, forty-two, and forty-five- Scaife and Richard Hannay find a place called Trafalgar Lodge, which is what the thirty-nine stepped staircase lead to.

There is only one spiral staircase. But it contains about 354 steps.
A spiral staircase is actually a very good analogy for DNA. The railings are like the chains of Deoxyribose (the type of sugar that gives DNA its name) that give the DNA molecule its shape. The steps in the staircase would represent the base pairs (made up of Adenine, Guanine, Thymine, and Cytosine) that contain the genetic information.
There are several steps that must be taken in order to build a spiral staircase for a home. A pole must first be created. The risers come next and then a handrail must be attached.

An internal spiral staircase is visible in this picture: http://en.wikipedia.org/wiki/File:Statue_of_Liberty_interior.jpg
Do not confuse stairs with steps or treads! All depends on floor to floor height. Floor to ceiling 8 ft. + floor thickness (8 to 12 in.) would give you approx. 10 or 11 steps. but my answer would have to be 1 (one), there is one stair in a standard spiral staircase

The Grand Staircase on Titanic (and Olympic) had twelve steps at the bottom.
Big Ben does not have a lift installed as there would not be enough room to install one due to the spiral stone staircase.
Steps, stairs, escalator, and stairway are all synonyms of staircase.
