nuclear DNA is like something the height of Everest packed into a golf ball

Categories: Comparisons

An example of an everyday comparison used in popular science writing:

"If you stretched out the DNA from one human cell it would reach for two metres, assuming you joined up the material from all the chromosomes. But this DNA has to fit into the nucleus of a cell, and the nucleus has a diameter of just one hundredth of a millimetre.

This is like trying to fit something that is the vertical height of Mount Everest in to a capsule the size of a golf ball."
