Early on during aggregation, gene expression requires the activity of cAMP-dependent protein kinase.

The addition of the 3’-CCA is catalyzed by the enzyme tRNA nucleotidyltransferase, which functions as a nontemplate-directed RNA polymerase.

Promoters with sequences closer to the consensus are generally “stronger” than those that match less well

The piRNAs which are 24–34 nucleotides long are derived in a manner that does not involve a dsRNA precursor

piRNAs are generated by processing long single-stranded transcripts covering so-called piRNA clusters found in the genome. This processing does not require Dicer.

The genetic code, in effect, is defined by two elements:

(1) the anticodons on tRNAs

(2) the specificity of the enzymes.

The protein DskA  also plays an important role. It binds to RNA polymerase and reduces the lifetimes of the rrn open promoters to a level at which they are responsive to changes in iNTP and ppGpp concentrations.
