Antitermination of RNA synthesis is a major mechanism of regulation in?
lytic phase of lambda phage
What is the purpose of maltose and magnesium in the media used for growing the host bacteria?
actually magnesium is a divalent ion so will help phage to easy adsorption at the host cell. maltose is a carbon source and binding the protein purpose is for adsorption.
What are phage vectors?
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".Commonly used vectors include plasmid, Lambda phage, cosmid and yeast artificial chromosome (YAC).
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).
What are temperate phages?
A phage that can enter into lysogeny with its host. A phage that can become a prophage.
How does the reproduction of HIV and lambda phage differ?
The Lambda Phage bacterial virus replicates itself whilst the HIV virus binds itself to existing cells and damages them. Lamba Phage increases with a "lysogenic" cycle, whilst the increase of HIV is known as "Lytic".
Lamda phage of E. coli?
It is the 'T4phage' or 'coliphage lambda'.
Antitermination of RNA synthesis is a major mechanism of regulation in?
lytic phase of lambda phage
When the bacteriophage DNA becomes part of the bacterial chromosome?
During phage infection into bacteria, it penetrates phage DNA into bacterium,which will be integrated in to the bacterial genome (chromosome) to replicate and synthesize phage molecules.
What is the purpose of maltose and magnesium in the media used for growing the host bacteria?
actually magnesium is a divalent ion so will help phage to easy adsorption at the host cell. maltose is a carbon source and binding the protein purpose is for adsorption.
What has the author Carol Gay Waghorne written?
Carol Gay Waghorne has written: 'Host participation in phage lambda development: involvement of the 'h+pR' gene product'

What does a phage inject when it attaches to a bacterium?
Dna and phage body
What is the need for phage titration?
PHAGE TRTRATION IS DONE SO AS TO FIND THE AMOUNT OF PHAGE PARTICLES PRESENT IN THE STOCK PHAGE TRTRATION IS DONE SO AS TO FIND THE AMOUNT OF PHAGE PARTICLES PRESENT IN THE STOCK
A virus that reproduces in a bacterium is called?
phage
What is another term for a lysogenic phage?
temperate phage
