Operon ap bio.

The lac Operon. The lac operon is a cluster of genes that code for a series of enzymes that work together to digest lactose into two monosaccharides: glucose and galactose. Here’s how the expression of these structural genes is controlled. When lactose is absent, the lac operon turns the expression of lactose-digesting enzymes off.

Apr 18, 2019 · Operator Definition. 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.
