Hi there, i'm going through a problem in here. I'm studying for replication cycles of viruses and, when writing about it, i ran into this:
There's lytic and Lysogenic cycle, right? Where Lytic cycle do it's job, and then lyses the cell (rupturing it for the release of krakkens!), and lysogenic, where as it may suggest, it MAY does the lyses, but has something to do with genes. So, the lysogenic cycle incorporates the viral genetic code into the host's cell genetic code, and in an unkown delimitated time the cell may lyses.
But, when talking about the Lythic cycle, it confuses me about if the process replication process is the same for "viruses (folded viruses)" and bacteriophages.
What i've wrote so far:
1. Attachment: the recognizement of the target is made by proteins on the virus and receptive proteins on the membrane, and then the virus will attach it to the cell's membrane.
2. Penetration: the virus may utilize either;
Endocitosis: where the cell will englobe (pseudopodes) the virus and make endossomes. If the virus is folded (that "shell" after capside) then the virus will release it's nucleocapside through the endossome's membrane
through the fusion of both folded virus and endosome's bilayer lipidic membrane affinity. If the virus isn't folded (it only has it's nucleocapsid), then it may lyses the endosome or even form pores on the endosome, easing it's way out.
Or it may use Fusion: If the virus is folded, it can fuse both virus and cell's bilayer lipidic membrane (cuz of it's affinity) and release it's nucleocapsid directly into the citoplasm. (Fusion may also happen on endocytosis as previously mentioned on 2. endocitosis)
Translocation: The virus is transported through the membrane by proteins (rare and no much information on why it happens).
This is what i've written so far (though the language isn't that bad on the Brazilian Portuguese writting.)
I'm consulting 4 different sources, being one wikipedia (shame on me) and 3 are english books on virology. But most of them (except wikipedia) gives the Lytic cycle example as a Bacteriophage, which makes me wonder, how the Lytic process differs from a Virus and a Bacteriophage are.
edit: Nevermind, i found the answer, which i should of simplied a long time ago. Not only bacteriophages, but other viruses also use lytic and lysogenic cycles for replication. All those examples with bacteriophages were confusing me.
