Operon Model

Definition

noun

A model conceptualized by Fran├žois Jacob and Jacques Monod depicting the coordinate expression of a group of genes.


Supplement

In this model, Jacob and Monod described the two sets of bacterial genes, i.e. the structural genes and regulatory genes, co-ordinately controlled to make a functional operon. An example is the lac operon.


Word origin: operon + model
