to examine the rna polymerase ( ec 2.7.7.6 ) specificity of rna maturation/utilization and transcriptional enhancement , we constructed a chimeric plasmid ( ppoli-cat ) in which a promoter for mouse rrna gene transcription was placed adjacent the coding sequences for chloramphenicol acetyltransferase ( cat ; ec 2.3.1.28 ) .
