Term
| Bacteriophages have three life cycles, what are they? |
|
Definition
| Lytic, Lysogenic, and Chronic |
|
|
Term
| The Lytic cycle results in what |
|
Definition
| lysis of the host cell to release the progeny phages |
|
|
Term
| The lysogenic cycle results in what? |
|
Definition
| The phage DNA integrates into the host chromosome as a prophage that is replicated along with the host DNA |
|
|
Term
| The Chronic cycle results in what? |
|
Definition
| Phages are released continuously without killing or lysing the cell. |
|
|
Term
| True or False. Bacteriophages have an unlimited host range due to restriction modification systems in bacteria. |
|
Definition
| False. Bacteriophages have a limited host range due to restriction modification systems in bacteria |
|
|
Term

|
Definition
|
|
Term
| Phage____ can be used as a cloning vector. |

Term
|
Definition
| is the protein shell of a virus. It encloses the genetic material of the virus. |
|
|
Term
|
Definition
| This is a phenomenon in which a bacterium of type x is able to distinguish a phage that has been grown in type x bacterium from one grown in a different type such as Y and is able to prevent the phage grown in Y from carrying out a successful infection |

|
Term
|
Definition
| refers to the breaking down of a cell, often by viral, enzymic or osmotic mechanisms that compromise its integrity. |
|
|
Term
|
Definition
| is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome. The integrated genetic material called a prophage can be transmitted to daughter cells at each subsequent cell division. |

| a fluid containing the contents of lysed cells |
|
|
Term
|
Definition
| a monolayer of host cells is infected with the virus at varying dilutions and covered with a semi solid medium such as agar, to prevent it from spreading indiscriminately. It forms little colonies that can be seen visually. |
|
|
Term
|
Definition
| is an RNA virus that is replicated in host cell via reverse transcriptase to produce DNA from its RNA genome. |
|
|
Term
|
Definition
| is a DNA polymerase enzyme that transcribes single stranded RNA into double stranded DNA. |
