gene amplification can regulate gene expression

Introduction - Genes do not operate to produce enzymes all the time. Each gene is normally more or less repressed (inactive); but, when a particular enzyme is needed, the relevant gene becomes active to bring about the production of that enzyme. A totally active g..

Gene Regulation in Eukaryotes - In eukaryotes, the genes that code for the enzymes needed to catalyse the various steps of a particular metabolic pathway may not be adjacent or even be in different chromosomes. However, these genes are regulated by ..

This gene controls the operator gene in cooperation with a chemical substance called inducer present in the cytoplasm. A regulator gene is not necessarily adjacent to the operator gene which it controls. The regulator gene codes..

The important characteristic of the gene is to store and express the genetic information that will contribute towards the phenotype, and will be passed on to successive generatio..

Gene Regulation in Prokaryotes - Bacteria cells can regulate the synthesis of enzymes in such a way that the enzymes are produced only when the substrates which these enzyme utilise are present in the ce..

An operon is the unit of transcription. When excess protein is present, it is no longer economical for the cell to use up its energy and materials in the synthesis of enzymes that are not immediately needed. Hence, the protein synthesis is stopped. This is clearly advantageous for the cell. Ge..
