"The usage of multiple reading frames leads to the possibility of overlapping genes; there may be many of these in viral, 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 ribosome may shift from one frame to another during translati… " - Reading frame mutation

WebMar 18, 2024 · As one type of gene mutation, the frameshift is defined as protein translations that start not at the first, but at the second (+1 frameshift or +1 fs) or the third (–1 frameshift or –1 fs) of the codon. Due to the triplet nature of codons, the amino acid sequence of a protein is determined by contiguous triplets.
