restriction mapping and blot hybridization ( southern , 1975 ) studies indicate that a subset of these clones containing beta 1 and beta 2 hybridizes to an adult beta-globin cdna clone ( maniatis et al. , 1976 ) more efficiently than to a human gamma-globin cdna clone ( wilson et al. , 1978 ) , while another subset containing beta 3 and beta 4 displays the converse hybridization specificity . beta 1 was identified as the adult beta-globin gene , while beta 2 , beta 3 and beta 4 have not been identified with any known rabbit globin polypeptides .
