Gene Expression
In all organisms, there are two major steps separating a protein-coding gene from its protein: First, the DNA on which the gene resides must be transcribed from DNA to messenger RNA (mRNA); and, second, it must be translated from mRNA to protein. RNA-coding genes must still go through the first step, but are not translated into protein. The process of producing a biologically functional molecule of either RNA or protein is called gene expression, and the resulting molecule itself is called a gene product.

Famous quotes containing the word expression:
“A work of art is an abstract or epitome of the world. It is the result or expression of nature, in miniature. For, although the works of nature are innumerable and all different, the result or the expression of them all is similar and single.”
—Ralph Waldo Emerson (1803–1882)
