the production of products by a gene that cause the appearance of the corresponding protein or phenotype; -- of a gene or of an organism with a specific gene; as, the expression the beta-galactosidase positive phenotype,

The process by which a gene's coded information is converted into the structures present and operating in the cell. extracellular matrix - Any material produced by cells and secreted into the surrounding medium.

The ability of a gene to function within a cell in such a way that the gene product is formed.

Describes the way that a gene is read

of a gene, activity. It is shown by production of RNA or protein.

Production of an observable phenotype by a gene - usually by the synthesis of a protein.

A measure of the presence, amount, and time-course of one or more gene products in a particular cell or tissue. Expression studies are typically performed at the RNA (mRNA) or protein level in order to determine the number, type, and level of genes that may be up-regulated or down-regulated during a cellular process, in response to an external stimulus, or in sickness or disease. Gene chips and proteomics now allow the study of expression profiles of sets of genes or even entire genomes.

the process by which a gene's coded information is converted into the structures present and operating in the cell. Expressed genes include those that are transcribed into mRNA and then translated into protein and those that are transcribed into RNA but not translated into protein.

generation of a messenger RNA (mRNA) copy of a gene encoded in an organism’s DNA.

To "express" a gene is to cause it to function. A gene which encodes a protein will, when expressed, be transcribed and translated to produce that protein. A gene which encodes an RNA rather than a protein (for example, a rRNA gene) will produce that RNA when expressed.

In molecular biology and biotechnology: the event of mRNA production and protein synthesis as a result of the activity of the corresponding gene. Both mRNA and protein level measurements are valid tests for gene expression, even if they give different results.

The physical manifestation of the information contained in a gene.

(genetics) the process of expressing a gene

a vital response to stress and by the criterion of their inducibility, mammalian SINEs behave like regulated cell stress genes

Production of the gene product. Expression rate ususally depends on environmental and other conditions ans is regulated by promotors and additional regulatory elements. Expression not subject to regulation is called constitutive expression

production of a gene[ back

Production of the desired trait (e.g., protein concentration) in a transgenic plant. Expression varies with the gene, its promoter and its insertion point in the host DNA.

The process of converting genetic information into RNA and protein for use in the cell. Every gene is not expressed at the same level and at the same time. Expression patterns, easily analyzed using microarray technology, can give a lot of information about the roles genes play in different situations, such as disease and health.

manifestation of the genetic material of the organism

The step to interpret the cell's genetic information into a specific protein.

not all genes are active. When a gene is read and the product of the gene (always including RNA and usually a protein) is produced, the gene is said to be expressed

In genetics, manifestation of a characteristic that is specified by a gene. With hereditary diseases, for example, a person can carry the gene for the disease but not actually have the disease. In this case, the gene is present but not expressed. In industrial biotechnology, the term is often used to mean the production of a protein by a gene that has been inserted into a new host organism.

A gene is said to express when it is active and responsible for the production of a protein, or products which alter cell function.

The translation of a gene to produce a protein. In recombinant methods expression is usually directed to produce large quantities of a target protein.

a highly specific process in which a gene is switched on at a certain time and begins production of its protein, resulting in the manifestation of a characteristic that is specified by a gene. Genetic predispositions to disease can occur, for example, if a person carries the gene for a disease but it is not expressed.

not all genes possessed by an organism will result in detectable physical traits or differences in that organism; the genes that do are expressed. Dominant genes are always expressed, but recessive genes may be present for many generations without physical expression in the phenotype.

Conversion of genetic information in corresponding protein

When a gene has an effect on how the offspring forms, that gene is said to be expressed.

the manifestation of a characteristic specified by a gene; also refers to the production of proteins by a genetically engineered organism.

The transcription and translation of a gene.

The process by which the information in a gene is used to create proteins

In relation to genes, the phenotypic manifestation of a trait.

The expression of a gene product.
