Lysogenic, or temperate, bacteriophage can undergo which type of life cycle?
Lysogenic, or temperate, bacteriophage can undergo which type of life cycle?
A. Lytic cycle
B. Lysogenic cycle
C. both A and B at the same time
D. Either A or B, depending on conditions
Homework Answers
Answer is option-D.
The bacteriophage infects the bacteria and injects the genetis material after that it chooses either of the life cycle, lytic (virulent) or lysogenic( temperate) life cycle. In lytic cycle the bacterial cell ultimately bursts or dies and in lysogenic it multuplies in number.

Review Each temperate (or lysogenic) bacteriophage (e.g., lambda, 434, P22) encodes its own repressor protein. The repressor binds to six binding sites within the phage genome. These sites can also be bound by a second transcriptional repressor encoded by the phage, called Cro. The pattern of binding of repressor and Cro to these sites determines whether the phage grows lytically or lysogenicaly. Launch the molecular model of the temperate bacteriophage repressor to explore its structure. Then, answer the questions. Launch...

A bacteriophage with a lytic life cycle develops a mutation that allows it to now also go through the lysogenic cycle. How would this provide an evolutionary advantage over the other bacteriophages that can only spread through lytic cycles?

which of the following regarding transposition is true
Which of the following regarding Transposition is TRUE? Transpositon requires the Ffactor. Transposition is a form of horizontal DNA transfer through the cutting and relocation of genetic material from one cell to another. Transposition is a form of genetic change and amplification, Transposition requires a sex pilus. The main difference between genetic replication and transposition is genetic material is duplicated during replication and is only moved during transposition Which of the following...

The bacteriophage used in this experiment reproduces by the
lytic cycle. Suppose a similar experiment were conducted with a
bacteriophage that uses the lysogenic cycle. How would the effect
on the infected bacteria MOST likely differ?
A. The bacteriophage would attach to the bacteria and reproduce
in the extracellular space.
B. The bacteriophage would become permanently dormant and
unresponsive to environmental cues for reproduction.
