To examine viral replication products in detail, DNA was extracted at 48 hours post infection (hpi) from cells treated with ATRi (ATR inhibitor VE-821 [35]), ATMi (ATM inhibitor Ku-55933 [36]), both ATRi and ATMi, or the solvent DMSO from 20 to 48 hpi. The gene discussed is ATR; the disease is infection.
