Double Helix

Real World Example

Imagine trying to untangle a pair of twisty earbuds that have been jumbled in your pocket. Just like those earbuds, the DNA molecule is structured in a twisted shape that is both compact and intricate. The twisted ladder shape of the DNA, known as a double helix, can be compared to the earbuds because both involve long strands that coil around themselves in a specific pattern, with the DNA's rungs made of chemical bases pairing up like the left and right earbuds aligning to create a functional structure.
