in an experiment designed to find sequences common to a skeletal muscle cdna library and an x chromosome specific library , we have isolated cdna clones corresponding to glyceraldehyde 3 phosphate dehydrogenase ( gapd ) , ( whose gene is assigned to chromosome 12 ) , and a dna fragment from the x chromosome short arm which contains an intron-less gapd pseudogene .
