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:
“There are obvious places in which government can narrow the chasm between haves and have-nots. One is the public schools, which have been seen as the great leveler, the authentic melting pot. That, today, is nonsense. In his scathing study of the nation’s public school system entitled “Savage Inequalities,” Jonathan Kozol made manifest the truth: that we have a system that discriminates against the poor in everything from class size to curriculum.”
—Anna Quindlen (b. 1952)
“It is not only their own need to mother that takes some women by surprise; there is also the shock of discovering the complexity of alternative child-care arrangements that have been made to sound so simple. Those for whom the intended solution is equal parenting have found that some parents are more equal than others.”
—Elaine Heffner (20th century)
