Abstract

Based on the fact that ribonucleic acid (RNA) synthesis occurs in vitro, a system in which the incorporation of radioactive orotic acid into the RNA of the nucleus of Iraqi dates was devised. Orotic acid‐6‐^14^C, and substrates necessary for the synthesis of nucleotides, stimulated the incorporation of orotic acid‐6‐^14^C into the RNA of the nucleus. In addition, a system was devised to test the hypothesis that each of the ratios of ATP/GTP and UTP/CTP, respectively, was a factor in stimulating RNA synthesis in different varieties.

The best incorporation of UTP‐^3^H into nuclear RNA was observed, and varied according to the date used and depended on the ATP/GTP ratio, and the best incorporation of ATP‐6‐^14^C into nuclear RNA was observed and varied according to the date used and depended on the UTP/CTP ratio. This in vitro system provides a method for studying RNA synthesis in different Iraqi Dates.
