When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What kind of cell does a phage infect?
Vidiian cells
What is the difference between virulent phage and prophage?
temperate refers to the life cycle some phages are able to perform. A temperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium.The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).So they are both the same in that they both require a host cell to reproduce. They both can have lytic lifecycles but only the temperate phage can "hitch a ride" in the host cell by integrating into the genome.
What is the phage DNA that is integrated into a host cell's chromosome is called a?
Phage DNA that is integrated into a host's cell chromosome is a bacteriophage. They behave as lytic or lysogenic. Lytic breaks open the host after replication, , lysogenic does not destroy the host.
Identify the terms endocytosis and exocytose and distinguish between them?
endocytosis is the movement of a substance into a cell by a vesicle. while the movement of a substance by a vesicle tot eh outside of a cell is called exocytosis
When a phage attaches to a bacterium what does the phage inject and what stays attached to the cell?
The part that remains outside is called the capsid or protein coat.
When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage
What kind of cell does a phage infect?
Vidiian cells
4 substance that enters and leaves through the cell membrane?
food enters, waste leaves
Is the f plus cell the recipient cell?
transfer of genes via a phage

What is the cell process called when a higher concentration of substance is outside the cell?
Exo-osmosis
The substance outside animal cells?
I believe it is the cell membrane!
What does phage DNA do once inside the host cell?
Once inside the host cell, phage DNA utilizes the host cell's machinery to replicate itself. It takes over the cellular processes and redirects them towards the production of new phages. The phage DNA is transcribed and translated to synthesize the necessary components for phage assembly, ultimately resulting in the formation of progeny phages inside the host cell.
What is a gel-liked substance outside the nucleus of a cell?
This is called the CYTOPLASM.
What phage in the reproductive cycle kills the bacterial host cell?
lytic
