Operon theory. The Operon theory proposed by Francois Jacob and Jacques Monod explains the evolutionary origin and dynamics of the gene regulation performed by the complex operon circuits that coordinate and reduce noise during biochemical signal processing. Answer and Explanation: 1

The Lac Operon. The lac operon, consisting of the three structural genes (lacZ, lacY and lacA) for metabolism of lactose and the upstream regulatory sequences (lacP and lacO), is an example of an inducible operon. Products of the structural genes are needed for uptake of lactose by the cell and its breakdown to glucose and galactose.

Operon: Operon is an essential part of DNA that contains a set or group of genes. The operon is considered to be the basic unit of DNA. It works under the influence of a single promoter. Many genes are co-transcribed to well define the operon. Answer and Explanation: 1

Operon: An operon is a functional unit of DNA that will contain the necessary genes under the control of a single promoter. Operons are characteristic of prokaryotic organisms, and are not found often in eukaryotic organisms. Answer and Explanation:

How does the Trp-operon control the production of tryptophan? Fill in the blank. The operon is turned _____ when lactose is present. Describe how enzymes function. The inducer of the lactose operon in E. coli is a. CAP. b. cAMP. c. allolactose. d. glucose. e. galactose. Explain how peptide hormones and steroid hormones affect the metabolism of ...

In operon A, the repressor is active by default, and molecule X is an inducer. What will happen if levels of molecule X increase? a. Genes within the operon will be expressed to a greater degree b. Genes within the operon will be expressed to a lesser d; Select the correct answer.

b. The lac operon is usually turned on in the presence of any sugar. c. The lac operon is usually turned on in the presence; Explain how the lac operon is regulated by repressor protein and CAP to ensure full activation under conditions where lactose is both available and required as a carbon source. In the bacterial lac repressor, which of ...
