Genetic Regulation Prokaryotes Enhancers differ from promoters in that their orientation can be inverted without effect they are restricted to a specific gene they initiate transcription they are adjacent to the start codon their orientation can be inverted without effect they are restricted to a specific gene they initiate transcription they are adjacent to the start codon ANSWER DOWNLOAD EXAMIANS APP
Genetic Regulation Prokaryotes Why are several structural genes regulated as a unit in bacteria? It allows coordinating regulation of genes with a common function An accident of evolution None of these The bacteria chromosome is so small; many different genes must be controlled by the same promoter It allows coordinating regulation of genes with a common function An accident of evolution None of these The bacteria chromosome is so small; many different genes must be controlled by the same promoter ANSWER DOWNLOAD EXAMIANS APP
