Well, hope you have idea about the tRNA.
the 5s tRNA genes were the first eukaryotic genes for which the promoter structure and transcription factor requirements were determinded. Researchers found that the promoter for RNA polymerase III is within the transcribed region. this internal promoter is called the internal control region(ICR).
the tRNA genes also have internal promoters, while snRNA genes transcribed by RNA polymerase III typically have promoters upstream of the genes.
If U have doughts yet, let me know.
