Operon Model

The model proposed by Jacob and Monod that describes the way certain genes are either active or inactive, depending on whether there is a need for them to be active.

The hypothesis is a prime example of effective and efficient biology at work, where resources are only used when needed. A more elaborate explanation of the operon hypothesis can be found in the [[control of Growth and development tutorial.

Help me come up with a model please

... following DNA. It's not known whether they are part of the same gene, operon or whatever but they are on the same chromosome. reg1--------reg2-------X-------Y ... when it's deleted, they only work in cis. I am trying to come up with a model that may egulate teh expression of Protein X and Y and ...

Gene expression in Prokaryotes, Oops!?!

... If you have difficulty understanding those concepts, try looking for a model, e.g the classical Lac operon. Its easier to correlate the concepts with some model that you see. I have an animated ...
