The selective forces acting to keep these genes together could indeed be different when the run is composed of different functional classes.
This manual selection process does not appear to bias the results in any way (for example, by eliminating a certain functional class of genes).
These genes were assigned into functional classes and characterized as up- and down-regulated.
Some functional classes of genes are more likely to be bidirectionally paired than others.
These Pfam family pairings may suggest that the two domains are associated with a distinct functional class.
Rules allow for a rower to compete in a higher functional class than they are currently classified.
Users can also browse through the entries by their identifier or by functional class.
The definition of functional classes and improved access to information associated with individual genes partly makes up for this lack of perspective.
They are usually designed with long-distance travel in mind and are not as common as the other two functional classes of roads.
Operon prediction is even more accurate if the functional class of the molecules is considered.
