The nucleus in the living yeast

  • Saraswathy Royan

1. There appears to be a large measure of agreement regarding the identification of the homogeneous body in the yeast cell as the nucleus. The differences relate only to the nuclear nature of the vacuole.

2. In a 120-hr. culture of a strain ofS. cerevisiœ, the appearance of the nucleus and vacuole under ordinary, phase contrast and dark ground illumination is described. Each appears to possess a membrane delimiting it from the cytoplasm. Can it be that yeast is bi-nucleate?
