In [[biology]], a '''reading frame''' is a contiguous and non-overlapping set of three-[[nucleotide]] [[codons]] in [[DNA]] or [[RNA]]. There are 3 possible reading frames in a [[mRNA]] strand and six in a double stranded [[DNA]] molecule due to the two strands from which transcription is possible. This leads to the possibility of overlapping [[gene]]s and there may be many of these in bacteria.<ref name=Johnson_2004>{{cite journal | author = Johnson Z, Chisholm S | title = Properties of overlapping genes are conserved across microbial genomes. | journal = Genome Res | volume = 14 | issue = 11 | pages = 2268-72 | year = 2004 | id = PMID 15520290}}</ref> Some viruses e.g. [[HBV]] 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]]. It is distinct from a [[frameshift mutation]] as the nucleotide sequence (DNA or RNA) is not altered only the frame in which it is read.
