Complementation of adenovirus type 5 host range mutants by adenovirus type 12 in coinfected HeLa and BHK-21 cells

We have studied the ability of adenovirus type 12 (Ad12) to complement the Ad5 transformation-defective host rang (hr) mutants during infection of human cells (HeLa) or hamster cells (BHK-21). The group I mutant hr3 (mapped within 1.3 to 3.7 map units), which is incapable of synthesizing viral DNA, was complemented for both DNA synthesis and infectious virus production in nonpermissive HeLa cells during coinfection with Ad12. Similarly, the …
