Size and Complexity
The entire nuclear pore complex (NPC) has a diameter of about 120 nanometers, the diameter of the opening (functional diameter) is about 9 nanometers wide and its "depth" is about 200 nanometers. It had been suggested that the pore can be dilated to around 39 nanometers to allow molecule passage. The molecular mass of the mammalian NPC is about 120 megadaltons and it contains approximately 30 different protein components, each in multiple copies. In contrast, the yeast model organism Saccharomyces cerevisiae is smaller, weighing only 66MDa.

Famous quotes containing the words size and/or complexity:
“Learn to shrink yourself to the size of the company you are in. Take their tone, whatever it may be, and excell in it if you can; but never pretend to give the tone. A free conversation will no more bear a dictator than a free government will.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The price we pay for the complexity of life is too high. When you think of all the effort you have to put in—telephonic, technological and relational—to alter even the slightest bit of behaviour in this strange world we call social life, you are left pining for the straightforwardness of primitive peoples and their physical work.”
—Jean Baudrillard (b. 1929)
