## Eukaryotic genes are divided into three categories according to the machineries by which they are transcribed. Ribosomal RNA genes (rDNA) are the only ones that are transcribed by RNA polymerase Iand are under diflerent control from other genes transcribed by RNA polymerase 11 or III. None the le
Ribosomal R N A (rRNA) contents were determined in 16 maize genotypes whose individual rRNA gene numbers varied from 5000 to 23,000 per 2C nucleus. Analytical polyacrylamide gel electrophoresis of total R N A showed that no obvious relation existed between rRNA gene number and rRNA content. Only two
