gene expression

The process of producing a protein from its DNA- and mRNA-coding sequences.

The process by which a gene produces mRNA and protein, and hence exerts its effect on the phenotype of an organism.

(JEEN ek-SPREH-shun) The process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

The process by which proteins are made from the instructions encoded in DNA. See also gene, protein

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 (e.g., transfer and ribosomal RNAs).
