FIG 2 .

Examples of simple duplications (category I). (A) The beta-actin control panel in the top left is identical to the panel in the bottom right (green boxes), although each panel represents a different experimental condition. This figure appeared in reference 27 and was corrected in reference 28. (Reproduced with permission from the publisher.) (B) The panels shown here were derived from two different figures within the same paper (reference 29; corrected in reference 30). Two of the top panels appear identical to two of the bottom panels, but they represent different experimental conditions (red and blue boxes). (Figure reproduced under the Creative Commons [CC BY] license.) All duplications might have been caused by honest errors during assembly of the figures.
