Properties of Lac Operon | Genetics

In this article we will discuss about the properties of lac operon. Also learn about the role of cyclic AMP in lac operon. i) Products of all genes are transcribed in a single mRNA, called polygenic or poly­cistronic, starting from single promoter site. ii) mRNA of lac operon mol wt. 1.7 x 106 daltons is far greater than the need [...]

Operon: Definition, Features and Modulation | Genetics

In this article we will discuss about:- 1. Definition of Operon 2. Features of Operon 3. Effector Control of Messenger Synthesis 4. Polarity 5. Modulation. Definition of Operon: In 1961 two Nobel laure­ates, Jacob and Monod, postulated the exis­tence of new genetic unit, the operon to explain the integrated control of the action of genes in a biosynthetic pathway in [...]
