Questions regarding lac/trp operons

... responsible for manufacture of trp. In this case (low trp levels - want to produce trp) attenuation will not occur (because the ribosome stalls at attenuator, antiterminator forms, transcription can proceed to trp genes) and so expression will proceed CONSTITUTIVELY until a certain point where ...

... Gray) homolog of the floral homeotic gene LEAFY (PTLF), which could be used to impart male and female flower sterility, to that of three candidate attenuator-gene promoters: the cauliflower mosaic virus (CaMV) 35S basal promoter, the CaMV 35S basal promoter fused to the TMV omega element and the ...

question(emergence)--feedback inhibition

... RNA created during translation can make secondary structures and interact with DNA. In bacteria Translation and transcription are simultaneous. An attenuator region is a region in the beginning of the mRNA, a "protein" is being translated in that region but it has several codons in a row for the ...
