abstract：:Differential expression of the genes expressing Pap pili in Escherichia coli was suggested to involve mRNAs with different stabilities. As the result of a post-transcriptional processing event, a papA gene-specific mRNA product (mRNA-A) accumulates in large excess relative to the primary mRNA-BA transcript. Our result...
