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