Marburg virus lytic or lysogenic?
There is a specific difference between the 2 cycles. In the Lytic cycle, the virus DNA/RNA remains separate from the Host's DNA. In the Lysogenic cycle, the virus DNA/RNA is incorporated (combined) into the host's DNA. Any virus injects its DNA into a host's cell. No matter what, in both cycles, the host cell ends up bursting and releasing the viruses. The Marburg virus incubates (grows) inside a host's cell, usually from 5-7 days, but can range from 3-10 days overall. It also produces new viruses which release into the organism (in this case, the human or primate). The Marburg Virus goes through both lytic and lysogenic cycles.
What are the phages called that are capable of using both modes of reproduction?
Phages that are capable of using both the lytic and lysogenic modes of reproduction are called temperate phages. In the lysogenic mode, temperate phages integrate their DNA into the host genome, while in the lytic mode, they replicate and cause cell lysis.
Is a provirus a temperate virus?
Yes, a provirus is a type of temperate virus. A provirus is a form of a virus that has integrated its genetic material into the host cell's DNA, remaining dormant until it is activated. Temperate viruses can exist in both the lytic and lysogenic cycles, with the lysogenic cycle involving integration of viral DNA into the host genome to form a provirus.
What is the difference between a virulent phage and a temperate phage?
A virulent phage only follows the lytic lifecycle, where it infects the host cell, replicates, and then lyses the cell to release new phages. In contrast, a temperate phage can follow both the lytic and lysogenic lifecycle. In the lysogenic cycle, the temperate phage integrates its DNA into the host genome, replicating as part of the host cell's DNA without causing immediate cell lysis.
Why does a virus enter a cell?
it primarily performs as a synthetic mutant antibody. When this occurs it becomes latent. As this occurs the cell becomes permeable, allowing for mutation. It's almost like going shopping for shoes, but coming home with a purse.
