Multiple Reading Frames
The usage of multiple reading frames leads to the possibility of overlapping genes; there may be many of these in virus, prokaryote, and mitochondrial genomes. Some viruses, e.g. Hepatitis B virus and BYDV, use several overlapping genes in different reading frames.
In rare cases, a translating ribosome may shift from one frame to another, a translational frameshift. This is distinct from a frameshift mutation, as the nucleotide sequence (DNA or RNA) is not altered—only the frame in which it is read.

Famous quotes containing the words multiple, reading and/or frames:
“Combining paid employment with marriage and motherhood creates safeguards for emotional well-being. Nothing is certain in life, but generally the chances of happiness are greater if one has multiple areas of interest and involvement. To juggle is to diminish the risk of depression, anxiety, and unhappiness.”
—Faye J. Crosby (20th century)
“...what a thing it is to lie there all day in the fine breeze, with the pine needles dropping on one, only to return to the hotel at night so hungry that the dinner, however homely, is a fete, and the menu finer reading than the best poetry in the world! Yet we are to leave all this for the glare and blaze of Nice and Monte Carlo; which is proof enough that one cannot become really acclimated to happiness.”
—Willa Cather (1876–1947)
“... though it is by no means requisite that the American women should emulate the men in the pursuit of the whale, the felling of the forest, or the shooting of wild turkeys, they might, with advantage, be taught in early youth to excel in the race, to hit a mark, to swim, and in short to use every exercise which could impart vigor to their frames and independence to their minds.”
—Frances Wright (1795–1852)
