Overlapping genes refer to a group of genes that share the same DNA sequence in certain regions. These genes are located very close to each other on the same strand of DNA in genome and have the potential to produce two or more distinct proteins. Synonyms for overlapping genes include ambisense genes, bicistronic genes, convergent genes, and partially overlapping genes. Ambisense genes contain codons on both strands of DNA, whereas bicistronic genes contain two separate coding regions. Convergent genes are those where the transcription of two separate genes overlaps on opposite strands of DNA, and partially overlapping genes share some, but not all, of their nucleotide sequences. The study of overlapping genes is important in biotechnology and genetic research.
