Nuclear membrane and chromatin network

Abstract

ARR et al. 1-3 were pioneers in the study which led to the discovery of a definite localization of the chromatin in relation to the nuclear membrane when they found that in the somatic cells of the cat the sex chromatiu is located at the nuclear membrane. BURGOS* demonstrated the accumulation of Feulgen reactive material on the inner aspect of the nuclear membrane in unfertilized eggs of Arbacia punetulata, and GA'x "5 studied the relations between chromatin and nuclear membrane outpocketings. However, the re]ation between chromatin network and the membrane in the interphase nucleus remains practically unexplored. In this paper we study a certain relation often observed between chromatin and nuclear membrane in the interphase nucleus of meristematic cells.
