The article presents information related to manipulation in the microbiology paper published by scientists at Taiwan-based National Chung Hsing University in the October 20, 2006 issue of the periodical "Cell." The paper, which questioned prevailing views of how transcription of a gene's DNA begins in bacteria, was challenged publicly on 16 November 2006 when an anonymous posting appeared on an electronic bulletin board run by Chinese students in the U.S. The posting alleged that many images in the paper had been manipulated. However, Ban-Yang Chang, the corresponding author of the paper has denied the allegation and stated that the conclusion made in paper is true on the basis of their data.
