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:
“There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period.”
—Auguste Rodin (1849–1917)
“Of all the diversions of life, there is none so proper to fill up its empty spaces as the reading of useful and entertaining authors.”
—Joseph Addison (1672–1719)
“The bird would cease and be as other birds
But that he knows in singing not to sing.
The question that he frames in all but words
Is what to make of a diminished thing.”
—Robert Frost (1874–1963)
