Figure 4 Hyperlinks. (A) In situ hybridization pattern of Ipa-6d in an early Drosophila embryo. The user has selected gene Ipa-6d in the Sequence Map viewer and has pressed the Image button at the top of the browser window. This selection invokes a window showing the embryonic expression pattern of the Ipa-6d gene as determined by RNA in situ hybridization. (B) GenBank entry for cactus accessed through the Sequence browser. The user has selected the cactus locus, and has pressed the Get Info button at the top of the Sequence Map viewer display. The cactus GenBank record with HTML hyperlinks is returned in a new separate browser window (the lower box). The lower window has the full capabilities of typical browser windows in that the user is able to follow the hyperlinks shown in blue.
