The alarmone regulates the his operon positively by stimulating the primary promoter hisp1 under conditions of moderate amino acid starvation (4). We cover the basics in biology concepts at the secondary level. Such operons are constitutively expressed, meaning they are transcribed and translated continuously to provide the cell with constant intermediate levels of the. No, an operon is transcribed from a single promoter, so the mrna is a single stranded copy of the antisense strand of dna. The lac operon is an inducible operon; Upstream of the trpe gene is the promoter and the attenuator (figure 2). The first operon to be.
