Gene in 2003. The diagram of the gene structure was idiosyncratic to Gene; the organization of the page followed the NCBI conventions of the time by using a blue sidebar at the left to provide general information about Gene and other resources. Links to related data in other databases was accessed by clicking on the Links menu at the upper right.
