Representative transcripts observed to change more than twofold for triplicate hybridizations for each of Many biological functions are accomplished by altering two independent experiments (except for cdc28-4, which the expression of various genes through transcriptional (e.g. represents triplicate hybridizations of RNA from a single through control of initiation, provision of RNA precursors, experiment).
