'NUAGE'-CHROMOSOME ASSOCIATION IN METAPHASE SPERMATOGONIA OF THE NEWT, CYNOPUS PYRRHOGASTER

Abstract
The nuage, an electron dense cytoplasmic component specific to the germ line cell, was found to be closely associated with a metaphase chromosome in the spermatogenic cell of the newt, Triturus (= Cynops) pyrrhogaster. This finding suggests a possible relationship between both components at a certain stage of spermatogenesis.
