Why is DNA's shape important?

DNA is shaped being a twisted ladder. Imagine a ladder manufactured from rubber. If you held the lower of the ladder firmly and twisted the top, the shape you would create would be the same shape that your DNA provides. Researchers call this shape a new 'double helix'.

The rungs around the DNA ladder are called bottom pairs: these do the important job to be the instructions. These base pairs can break, allowing the sides from the helix to unravel (roll your mouse pointer on the image). This special property can be what allows DNA to replicate itself, and to act since the instructions.
