RESUMO
Synthesis of fd deoxyribonucleic acid (DNA) was stopped by transferring infected bacteria from 32 C into chloramphenicol or serine hydroxamate at 42 C, but not by addition of these antibiotics at 32 C, and not by a temperature change in the absence of antibiotics. The inhibition of fd DNA synthesis by serine hydroxamate at 42 C was reversed by excess serine. The ability to synthesize fd DNA at 42 C in chloramphenicol was rescued by delaying the addition of chloramphenicol for a few minutes after the transfer from 32 to 42 C. The colony-forming ability of abortively infected bacteria was also rescued from “killing” by delaying the addition of chloramphenicol after a transfer from 32 to 42 C.
