... or false: All virus particles produced from infected cells are infectious. I find this to be very confusing. On the one hand, some virions are non-infective if they become damaged or are missing part of the genome in the cell. I know that a virus particle is non-infective if it cannot replicate, ...

... lose their conformation and the lipid membrane degrades. Since HIV requires its envelope in order to be infectous, this also destroys the infective virus. Finally, RNA (HIV's genetic material) as such is an unstable molecule (when compared to e.g. DNA), which readily degrades outside its ...

... with viral DNA leads to replication of a prophage (a molecule of DNA )in the chromosome of the bacterial cell. The prophage is inactive, non-infective, but it will replicate each time the DNA in chromosome is replicated during cell divisions. it is possible that the prophage to get cleaved ...

... Phage P22 DNA is ds; M13 RF DNA (RF stands for “replicative” form, though I’m not quite sure what the II is for) is a ds circle, although the infective DNA is ss and would be resistant to lambda exonuclease. rRNA should be resistant to the exonuclease, does not have a typical melting curve, ...
