Variations in the structure of the nucleus in living yeast

  • Saraswathy Royan


1. The nucleus could be observed in the living cells from a 96–120-hr. culture of a strain ofSaccharomyces cerevisiœ.

2. It could be followed up during the processes of fixation, hydrolysis, staining and dehydration. In its staining reactions it is identical with the nucleus described by the early investigators.

3. Under the phase contrast microscope there is no uniformity in the architecture of the resting nucleus in living cells. It may be a homogeneous body or may contain denser areas or formed structures inside.
