ABSTRACT

In the past decade, high-throughput sequence technology has made 700 genomes fully sequenced as of October 2008 (https://www.ncbi.nlm.nih.gov/ genomes/lproks.cgi). In order to keep up with the sequencing pace, researchers have annotated coding genes of the genomic data and predicted gene function. This level of genome annotation is known as one-dimensional genome annotation [1]. The next grand challenge is to understand how gene products (either RNA genes or proteins) interact with each other and govern the

transcriptional rates of genes in the network. Such an annotation, a regulatory network annotation, is also known as two-dimensional genome annotation [1].
