An operator is a genetic sequence which allows proteins responsible for transcription to attach to the DNA sequence. The gene, or genes, which get transcribed when the operator is bound are known as the operon. Repressor proteins, which bind to the gene operator, can block transcription factors from binding to the operator. Build a gene network! The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.inducible operon - consists of structural genes (Y, Z, A) that code for enzymes that catabolize lactose for energy in E. coli - repressor is active when lactose levels are low - if lactose levels are too high, allolactose (isomer of lactose) acts as an inducer, binding to the repressor to deactivate it-> the genes for the enzymes are formed ...2.
