The data were normalized with regard to radioactivity and the amount of DNA bound to the hybridization membrane. Several distinct changes in the expression of ge

These metabolic tasks correlate with a strong proliferation and structural changes of the organelles. Future work will address the molecular factors responsible for these metabolic and structural changes.
