Templates for Looking at Gene Expression Clustering

We are in a new era in which biologists can selectively disrupt genes and design genes to perform specific tasks. However, genes do not function in isolation. In gene knock-out experiments, the deletion of a gene can have a disastrous effect in some cases, while in others the working constellation of genes compensates quite well for the gene’s absence (see Galli-Taliadoros et al. 1995). This suggests redundancy of gene function and combinatorial regulation of genes: a complex genetic network.
