| doublet microtubule | <cell biology> Microtubules of the axoneme. The outer nine sets are often referred to as doublet microtubules, although only one the A tubule) is complete and has 13 protofilaments. The B tubule has only 10 or 11 protofilaments and shares the remainder with the A tubule. A and B tubules differ in their stability and in the other proteins attached periodically to them, it is the dynein affixed to the A tubule attaching and detaching from the B tubule of the adjacent doublet that generates sliding movement in the axoneme.

The shape of DNA, much like a spiral staircase or twisted ladder. The stairway's railings are composed of sugars and phosphates. Its sides contain the patterned base pairs: A, T, C, and G. When a cell divides for reproduction, the helix unwinds and splits down the middle like a zipper in order to copy itself.
