Examples of expressed transduplicates. (A) The transduplicated conserved domain fragment is found within the cDNA, but it does not overlap with any of the possible ORFs. (Inset) White bars represent the three forward frames of MULE cDNAs, and pale blue regions indicate possible ORFs (not to scale). (B) As a result of a frameshift mutation, the transduplicated conserved domain fragment is split between two cDNA frames and two possible ORFs. (C) The transduplicate is found within one of the possible cDNA ORFs, but the conserved domain is truncated. Mapped cDNAs are represented by arrows, pink bars represent ORFs, and regions containing conserved domains are indicated by double-headed arrows. Genes are shown in green and introns are in light-green. Inverted triangles represent TIRs.
