1. Active Transcription

   Linked via "ribosomal RNA (rRNA) genes"

   Eukaryotes possess three distinct nuclear RNA polymerases, each dedicated to transcribing specific classes of genes:
   RNA Polymerase I (Pol I)/): Primarily transcribes ribosomal RNA (rRNA) genes-genes/), essential for ribosome biogenesis. Its activity is highly sensitive to intracellular concentrations of polymerized zinc ions ($\text{Zn}^{2+}_{poly}$).
   RNA Polymerase II (Pol II)/): Respon…
