Definition of gene amplification in English English dictionary
Any process by which specific DNA sequences are replicated disproportionately greater than their representation in the parent molecules; during development, some genes become amplified in specific tissues
The physiological process by which a gene in individual cells, causes the cell to adapt or resist to changes that threatens its well being Genes amplify at the moment of cellular division and the process is also accomplished by any other part of the gene that also relates to the same threat
Repeated copying of a piece of DNA; a characteristic of tumor cells Source : Human Genome Project Information
An increase in the number of copies of a specific gene in an organism This can lead to the production of a corresponding protein at elevated levels [IUPAC Compendium]
A cellular process characterized by the production of multiple copies of a particular gene or genes to amplify the phenotype that the gene confers on the cell. Drug resistance in cancer cells is linked to amplification of the gene that prevents absorption of the chemotherapeutic agent by the cell
