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 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
Is the f plus cell the recipient cell?
transfer of genes via a phage
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 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.
The substance a phage leaves outside its host cell?
the protein coat.
What phage in the reproductive cycle kills the bacterial host cell?
lytic
What is the type of cell division responsible for growth and repair?
Mitosis is the type of cell division essential for repair of tissues.
What is the difference between a virulent phage and a temperate phage?
In virology, temperate refers to the life cycle some phages are able to perform. Atemperate 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).
Mitosis also known as?
The M phase in cell cycle is the mitosis phase, where the cell performs mitosis.
When cytoplasm from a cell that is undergoing mitosis is injected into a cell that is in interphase what does the second cell do?
The second cell enters mitosis.
