For example, we may have a large number of points in space at certain distances from a central reference/origin point.

Suppose we have to lookup the points which are in a certain range of distances from our origin.

To illustrate this, we review the evolution of operational definitions of a gene over the past century—from the abstract elements of heredity of Mendel and Morgan to the present-day ORFs enumerated in the sequence databanks.

We then summarize the current ENCODE findings and provide a computational metaphor for the complexity.

This project represents a major milestone in the characterization of the human genome, and the current findings show a striking picture of complex molecular activity. The discrepancy between our previous protein-centric view of the gene and one that is revealed by the extensive transcriptional activity of the genome prompts us to reconsider now what a gene is.

While the landmark human genome sequencing surprised many with the small number (relative to simpler organisms) of protein-coding genes that sequence annotators could identify (∼21,000, according to the latest estimate [see ENCODE highlighted the number and complexity of the RNA transcripts that the genome produces. Here, we review how the concept of the gene has changed over the past century, summarize the current thinking based on the latest ENCODE findings, and propose a new updated gene definition that takes these findings into account.

This can be a tedious and slow process, especially if the number of queries is large and repetitive.

While sequencing of the human genome surprised us with how many protein-coding genes there are, it did not fundamentally change our perspective on what a gene is.

In contrast, the complex patterns of dispersed regulation and pervasive transcription uncovered by the ENCODE project, together with non-genic conservation and the abundance of noncoding RNA genes, have challenged the notion of the gene.

Finally, we propose a tentative update to the definition of a gene: A gene is a union of genomic sequences encoding a coherent set of potentially overlapping functional products.

Our definition sidesteps the complexities of regulation and transcription by removing the former altogether from the definition and arguing that final, functional gene products (rather than intermediate transcripts) should be used to group together entities associated with a single gene.
