Changes in the Subunit Structure of , RNA Polymerase During Sporulation,x and coat components of the spore and, finally, by the release of the mature spore from the mother cell. These morphological events are accompanied by changes in gene transcription. New classes of messenger RNA appear during sporulation (1), while the synthesis of ribosomal RNA is turned off in . (2) and . (3).

,Makroökonomische Entscheidungsmodelle,y to superinfection is due to the presence of repressor protein in the cytoplasm of the lysogenic cell. Being a temperate phage, P22 possesses more complicated regulatory processes than the virulent phages, which produce only one kind of response leading to lysis of the cells.

All these studies indicated the existence of regulated gene activity as expressed by differential gene expression. Such a regulation has been suggested as a basic molecular event behind the processes of cell differentiation and morphogenesis.
