Abstract

DNA-free minicells of Escherichia coli will not allow growth of phage T-7, nor is RNA synthesis stimulated by phage infection. Thus, these miniature cells seem not to contain in vivo RNA polymerase activity. However, DNA-dependent RNA polymerase activity can be unmasked in extracts with poly(dA-T) and Mn²⁺. This activity may represent a cytoplasmic pool of inactive RNA polymerase in normal cells.
