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:
“... the generation of the 20’s was truly secular in that it still knew its theology and its varieties of religious experience. We are post-secular, inventing new faiths, without any sense of organizing truths. The truths we accept are so multiple that honesty becomes little more than a strategy by which you manage your tendencies toward duplicity.”
—Ann Douglas (b. 1942)
“People who have been made to suffer by certain things cannot be reminded of them without a horror which paralyses every other pleasure, even that to be found in reading a story.”
—Stendhal [Marie Henri Beyle] (1783–1842)
“For laughter frames the lips of death—
Death frames the Singer and the Song.”
—Allen Tate (1899–1979)
