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.

“After which you led me to water
And bade me drink, which I did, owing to your kindness.
You would not let me out for two days and three nights,
Bringing me books bound in wild thyme and scented wild grasses
As if reading had any interest for me ...”
—John Ashbery (b. 1927)
“For laughter frames the lips of death—
Death frames the Singer and the Song.”
