may involve some self-assembly AND may involve the use of scaffolds.
randomly bump into the bacteria AND attach to proteins or carbohydrates on the bacterial surface
produced in a sequential manner AND used to customize the cell for viral production
may have a persistent infection AND may be a source of infection.
differ because bacteriophages leave the capsid outside the cell, while animal virus entry involves the entry of the whole nucleocapsid.
(all correct)-are extruded.-contain a positive-sense DNA strand.-have their DNA transformed to double-stranded DNA before replication and transcription occur.
may be lysogenic AND enters a lysogenic or lytic life cycle shortly after entering the host cell
may be used to grow viruses AND can be cultivated in vitro indefinitely.
(all correct)-replicate by converting normal host proteins into prion proteins. -responsible for "mad cow disease" can cause a similar disease in humans.-can be transmitted by consumption of dried or cooked food.that cause Spongiform Encephalopathy have the same amino acids but different folding properties from PrPc.
No, because the virus would depend too much on having the active machinery of a living cell for its replication. Without the ability of the cell to try to replace what is lost/damaged/used as the virus goes through its life cycle, the virus couldn't reproduce effectively.
(all correct)-the majority of phages are temperate.-when integrated into host DNA, the phage DNA is called a prophage. -lambda is a good example of a temperate phage.
are immune to infection by the same virus AND may have new properties.
(all correct)-is replicated.-is transcribed.-may get degraded by bacterial nucleases.
involves the transfer of a few specific genes, utilizes a defective virus AND only involves genes near the viral DNA integration site.
A virus that has lost some of its genetic material, and therefore cannot replicate within a new target cell
have an outer lipid bilayer membrane containing various proteins
probably keep the numbers of bacteria in check AND are active in passing DNA from one bacterium to another
is called a capsid, protects the nucleic acid, AND is involved in the recognition of host cell receptors by non-enveloped viruses.
attachment, penetration, transcription, replication of nucleic acid and protein, assembly, release.
