摘要: Abstract: We review three lines of research which are aimed at understanding transcriptional regulation the genes coding for 40S precursor rRNA in frog Xenopus. First we describe a method selectively labeling 5′ initiation terminus molecule. Using such terminally labeled precursors have mapped site transcription on rDNA and can show that is preceded by least 200 bp DNA whose sequence conserved. also find limited heterogeneity end
