- Gene amplification. Definition. noun. The process of duplicating a particular gene, causing the gene to increase in frequency inside the cell, as well as amplifying the phenotype (e.g. the proteins) that the gene confers (or code for). Supplement. Gene amplification is one way by which a gene can be over-expressed.

Transformation is the process by which the genetic content of a cell is changed. In the case of bacterial. transformation, DNA is introduced into bacterial cells.Transformation occurs naturally among bacteria. that are able to conjugate, a form of mating, but this is rare.ells that do not carry this gene are able to grow on normal nutrient media, but not on nutrient media containing ampicillin, whereas cells that do carry the Amp R gene grow on both nutrient media and nutrient media plus ampicillin. Transformation is the process by which the genetic content of a cell is changed.

- Split and merge into it. Answer by Acid36. Confidence votes 5.0K. The ampicillin resistance gene (AmpR) is called a selectable marker gene and is incorporated into several plasmids that are commonly used in a wide range of genetic engineering and molecular biology experiments.f antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all no … n-transformed bacteria, that don't have the antibiotic resistance.

Gene Expression and Regulation Gene expression is the process by which the genetic code-the nucleotide sequence-of a gene is used to direct protein synthesis and produce the structures of the cell. Genes that code for amino acid sequences are known as 'structural genes'. The process of gene expression involves two main stages:

- Gene expression is the process by which the inheritable information in a gene, such as the DNA sequence, is made into a functional gene product, such as protein or RNA. Gene expression is the process of taking genetic information in DNA and trans lating it into biological functions such as protein synthesis.

- 21 CFR 866.6040 – A gene expression profiling test system for breast cancer prognosis is a device that measures the RNA expression level of multiple genes and combines this information to yield a signature (pattern or classifier or index) to aid in prognosis of previously diagnosed breast cancer. gene expression profiling test system for breast cancer prognosis is a test that may require instrumentation for clinical multiplex test systems. Instrumentation for clinical multiplex test systems is regulated under 21 CFR 862.2570.

Gene Therapy Description: Gene therapy is when DNA is introduced into a patient to treat a genetic disease. The new DNA usually contains a functioning gene to correct the effects of a disease-causing mutation.1  Source: Genome Research Limited and Wellcome Trust Sanger Institute. |.ene Therapy. Gene therapy is an experimental technique for treating disease by altering the patient's genetic material. Most often, gene therapy works by introducing a healthy copy of a defective gene into the patient's cells.

- Image Credit: Main Image: Gene Amplification, also known as gene duplication or chromosomal duplication, is a cellular process in which multiple copies of a gene are produced. The result is an amplification of the phenotype, or expressed trait, associated with the gene.ot all gene amplification has great importance to evolution. Sometimes, the amplified trait dies with the single organism that experiences the gene duplication. This happens when a gene is over expressed and the trait it codes for is expressed to a level that is unhealthy to the organism.

Translations for gene expression Gene expression. Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as ribosomal RNA, transfer RNA or small nuclear RNA genes, the product is a functional RNA.n genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype. The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.

Gene regulation Sections. Definition. Gene regulation refers to the mechanisms that act to induce or repress the expression of a gene. These include structural and chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription, or mechanisms that modulate translation of mRNA.

Gene expression In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, i.e. observable trait. The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.xpression of a gene coding for a protein is only possible if the messenger RNA carrying the code survives long enough to be translated. In a typical cell, an RNA molecule is only stable if specifically protected from degradation.

Gene expression profiling in cancer Gene expression profiling in cancer. Cancer is a disease characterized by uncontrolled cell growth and proliferation. For cancer to develop, genes regulating cell growth and differentiation must be altered; these mutations are then maintained through subsequent cell divisions and are thus present in all cancerous cells.

- PCR is the enzymatic amplification of a specific DNA sequence in vitro9. This process uses multiple cycles of template denaturation, primer annealing, and primer elongation to amplify DNA sequences. It is an exponential process since the amplified products from each previous cycle serve as templates for the next cycle of amplification,
