Abstract
An active turnover of RNA-phosphorus assimilated after phage infection has been revealed. It was also found that chloramphenicol, when added 10 minutes after T2 infection, blocked the breakdown of RNA formed after infection, but not the synthesis of new RNA, indicating a correlation between RNA breakdown and protein synthesis. From these results it is concluded that the RNA, which is formed after infection, is distinct from the RNA of the host cell in metabolic activity.
