The Synthesis of Dna and Nuclear Protein by Gonocytes in the Testes of Normal and X-Irradiated Ratr

Abstract

It had previously been found that treatment of the testes of rats at 4 days of age with X-rays (300 r) suppressed mitotic activity in gonocytes and between 5 and 8 days of age these cells, together with their nuclei and nucleoli, became markedly increased in size.
