    "abstract": "We identify a set of 575 human genes that are expressed in all conditions\ntested in a publicly available database of microarray results. Based on this\ncommon occurrence, the set is expected to be rich in \"housekeeping\" genes,\nshowing constitutive expression in all tissues. We compare selected aspects of\ntheir genomic structure with a set of background genes. We find that the\nintrons, untranslated regions and coding sequences of the housekeeping genes\nare shorter, indicating a selection for compactness in these genes.",
