1)
A virus that infects bacteria is a
Retrovirus
Capsid
Bacteriophage
Prion
2)
Bacteriophage DNAs that have become integrated into the host cell chromosome are called
Plasmids
T-even bacteriophages
Prophages
Transposons
3)
Which of the following is NOT one of the bases in RNA molecule?
Adenine
Cytosine
Uracil
Thymine
4)
RNA is the genetic material of some
Viruses
Bacteria
Fungi
None of the above
5)
TRIzol reagent is a mono-phasic solution of
Isopropanol, Phenol
Phenol, Guanidine isothiocyanate
Isopropanol, Guanidine isothiocyanate
Chloroform, Phenol
6)
Which of the following is an example of protein denaturant used in RNA isolation
Ethanol
Isopropanol
Guanidine isothiocyanate
Tris
7)
A lysogenic cycle involves
Early lysis of the host cell
The ultimate formation of a prophage
Lysis by the lamda lytic protein
A period of genome integration
8)
When a virus kills the infected host cell in which it is replicating, the reproductive cycle is called as ----------------- cycle.
Phagocytic
Lytic
Viroidal
Endocytic
9)
Which of the following are not matched correctly:
Temperate virus –non –infecting virus
Virulent virus –lytic cycle
Lytic cycle –kills host cell
Lysogenic virus –genome becomes part of host genome
10)
A virus that can reproduce by either the lytic cycle or the lysogenic cycle is called
A virulent phage
A lysogenic phage
A temperate phage
A non virulent phage
11)
In this assay, the plaques on the agar plate are areas where:
Phages are growing
Infected bacteria have lysed

Infective; Retroviral
Retroviral; Infective
Lytic; Lysogenic
Lysogenic; Lytic
