Perpetuation of the Germ Line

  • Susumu Ohno

Abstract

A multicelular organism is a mortal. As such, a two-year-old mouse is a very old mouse indeed, Even with the best medical care, no would expect a mouse to live 5 years. In the case of man, gradual deterioration which accompanies aging appears to begm at about 30; a 100-year-old man is as rare as a 2-year-old mouse. Yet, in a strict sense, only the somatic cells of the body are mortals.
