Gene function of heterozygotes in phage T4

  • R. Hertel


Gene function of various T4-heterozygotes was tested. About half of the HETs containing wild type and anam-mutation disappeared under non-permissive conditions, if theam-defect concerned “early” functions. The same was found when phages, heterozygous forr+ and anrII-point-mutation, were adsorbed to K12 (λ). A much more extensive loss of HETs in K could be observed if anrIIA- and anrIIB-point-mutation (block-mutations showed different results) occurred together in a non-recombinant heterozygote. The findings provide evidence that one class of T4-heterozygotes has a heteroduplex DNA-structure.
