21. HNRPUL1 also participates in ATR protein kinase signalling pathways during adenovirus infection. 22. Adenovirus particles were inactivated on copper ( C11000 ) within 1 hour.23. Adenoviruses have so far been through three generations of development.24. But cells that are not infected with the adenovirus are impervious to ganciclovir. 25. A strain of adenovirus exists that has lost the p53-jamming gene. 26. Adenovirus has at least three genes for this purpose.27. It delivers a functional copy of the p53 gene using an engineered adenovirus . 28. Some adenoviruses under specialized conditions can transform cells using their early gene products. 29. Two types of canine adenoviruses are well known, type 1 and 2. 30. Virus isolation is the only way to identify the serotype of the adenovirus .
