Nonenveloped viruses can have the ability to pass from cell

_____ Nonenveloped viruses can have the ability to pass from cell to cell without leaving the cell. ______ Attachment of viruses to their cellular receptor is energy - dependent. _____ A virus may code for enzymes, but a virion will never include any enzymes. _____ Assembly of the base plate of T4 is fairly simple with few proteins involved.

Solution

All statements are false.

1. Nonenveloped viruses cause host cell lysis.

2. Attachment is not energy dependant but penetration is energy dependant.

3. A virion is complete virus with genetic material and protien coat and is a vector stage of virus. So if HIV virus code for reverse transcriptase its virion will also code for it.

4. Assembly of the base plate of T4 bacteriophage is complex.
