A conditional knockout allows gene deletion in a tissue or time specific manner. This is done by introducing short sequences called loxP sites around the gene.
Categorizations of gene function, such as those used in the Gene Ontology Project slot each gene into one category in a hierarchy of categories. They are helpful, but they ignore the fact that an individual gene has no function in isolation. Third, the goal of making a prediction makes sense only when there is a need for a prediction and when the system has sufficient regularity that making a prediction is possible.
