| 21. | It is not a structural protein found in a completed particle of the virus.
|
| 22. | The VP24 and VP35 structural proteins of EBOV play a key role in this interference.
|
| 23. | The left ORF encodes 4 non structural proteins ( NS1, NS2, NS3 and NS4 ).
|
| 24. | Late genes are expressed from 140 min to 48 hours post-infection, producing all structural proteins.
|
| 25. | The virus is 22 % RNA by weight, the other 78 % being structural proteins.
|
| 26. | NS3 protease, on the other hand, is responsible for the cleavage of non-structural proteins downstream.
|
| 27. | The late region encodes structural proteins L1 and L2.
|
| 28. | NP1 is a small non-structural protein that could induce apoptosis in transfection of HeLa cells.
|
| 29. | It is also used to manufacture structural proteins and useful to propagate the immune system.
|
| 30. | HPIV genomes are about 15, 000 nucleotides in length and encode six key structural proteins.
