Genes themselves do nothing except encode proteins. To make any given protein, the appropria

The alteration might be trivial: a mere re-adjustment, returning the cell to a status quo that has been transiently upset. But it might be radical, a dramatic change in appearance and behaviour.

A dog salivating at the smell of food, a flower opening in sunlight and a worm crawling towards moisture are examples of organisms responding to stimuli from their surroundings. All organisms respond to their surroundings in order to improv

If some of the “master documents” are missing or defective the consequences are potentially serious. Every cell must begin with a very accurate copy of its parent’s or parents’
