Hyper variable regions are usually called complementarity determining regions (CDRs).

Accordingly, iNTP stabilizes the open promoter complex, stimulating transcription. On the other hand, when cells are starved for amino acids, protein synthesis cannot occur readily and the need for ribosomes (and rRNA) decreases. Ribosomes sense the lack of amino acids when uncharged tRNAs bind to the ribosomal site where aminoacyl-tRNAs would normally bind.
