Zinc ions are differentially required for the transcription of ribosomal 5S RNA and tRNA in a HeLa-cell extract.
Chelation of divalent cations by 5 mM EDTA and subsequent removal by dialysis from a cytoplasmic HeLa cell extract leads to a complete loss of 5S rRNA transcription without affecting tRNA synthesis. Transcription complexes for 5S RNA can no longer be assembled in such a zinc-depleted extract and thi...
