During the lysogenic cycle of lambda (1) phagethe phage genome is integrated in the host chromosome where it is passed on to daughter cells through binary fission.the phage DNA is copied and accumulates in the cytoplasm. Then a trigger causes capsid proteins to be made and phages are assembled.the product of one prophage gene is made and it activates most of the other prophage genes.the viral genes immediately turn the host cell into a lambda-producing factory. Then the host lyses.0000

Bacteriophage are those viruses which are found to be in fact to the bacterial cell.

Which of the following is true of Generalized transduction? O creates defective virions that are missing the entire phage genome phage and host DNA are both packed in the capsid by error Cha type of Hirgone transfer Frequency is I in 10¹ O occurs during the lysogenic cycle
You are studying your favorite (hypothetical) bacteriophage named M277. It infects E. coli and stays dormant within the bacterial cell. How does a phage become dormant within a cell? Generally, describe the steps of infection by phage in this scenario
Certain environmental conditions such as exposure to UV light areknown to activate lysogenic λ prophages and cause them to progressinto the lytic cycle. UV light initially causes the repressor protein to be proteolytically degraded. Make a flow diagram showing the subsequent events that lead to the lytic cycle. (Note: The xis gene codes for an enzyme that is necessary to excise the λ prophage from the E. coli chromosome. The enzyme integrase is also necessary for this excision.)
Experimentally, when an E. coli bacterium already has a λ prophageintegrated into its chromosome, another λ phage cannot usually infectthe cell and establish the lysogenic or lytic cycle. Based on yourunderstanding of the genetic regulation of the phage λ reproductivecycles, why do you think the other phage would be unsuccessful?
In generalized transduction.... Choose from the answers below: random fragments of degraded bacterial DNA are packaged in phage particles. the maximum size of transduced DNA fragments is dependent on the size of the phage particles. the transducing DNA fragments are generated by faulty excision of a prophage from the host genome. a and b, but not c b and c, but not a
During the lytic replication cycle of the bacteriophage T4, the phage _________ remains outside the cell while the phage ________ enters the cell. A) capsid protein… tail fibers B) DNA… protein C) envelope… DNA D) enzymes… ribosome E) protein… genetic material F) RNA… capsid protein

Briefly describe the role of the Lambda repressor (cI) and cII activator to regulate the switch betweenthe lytic and lysogenic cycles of phage Lambda.

Why is a webbed plate capable of producing a higher lysate titer (pfu/mL) than a cleared plate? a.) A webbed plate has plaques that have gone through more rounds of replication because the number of host cells did not limit phage replication, creating exponentially more phage particles b.) A webbed plate has no more host available for replication, meaning the plate is full of exponentially higher amounts of phage c.) A cleared plate has less bacteria than a webbed plate, so there are more plaques present d.) A cleared plate contains more phage than a webbed plate because it started with a more concentrated phage sample
Which statement describes the difference between a lytic and lysogenic phage cycle? In a lytic cycle, new phage particles will be produced; in a lysogenic cycle, the phage DNA is passed to new cells but does not produce phage particles. In a lytic cycle, the host cell does not die; in a lysogenic cycle, the host is killed. In a lytic cycle, the phage DNA enters the host cell; in a lysogenic cycle, the phage DNA remains on the exterior of the host cell. In a lytic cycle, the phage DNA incorporates into the host genome; in a lysogenic cycle, the phage DNA does not incorporate into the host genome.
Which of the following events occurs in the lytic cycle of bacteriophage T4 infection but NOT in the lysogenic cycle? a.both digestion of host DNA and viral proteins synthesis b.attachment c.viral protein synthesis d.digestion of host DNA e.entry
