| 1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
| 2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
| Q1 ⇒ The sequence of nucleic acid in a variety of viruses and viral host, will find more similarities between viruses and their hosts than among different viruses [other wrong options] [Discuss in forum] |
| Q2 ⇒ The envelope of which of the following viruses is derived from the host cell nucleus? Herpesviruses [other wrong options] [Discuss in forum] |
| Q3 ⇒ In order for a virus to replicate the genome must be released in the cytoplasm [other wrong options] [Discuss in forum] |
| Q4 ⇒ The temperate phage that have no site specificity for insertion and may even be able to insert multiple copies of their DNA into a single bacterial chromosome is Phage Mu [other wrong options] [Discuss in forum] |
| Q5 ⇒ The most complex type of bacterial viruses having hexagonal head, a rigid tail with a contractile sheath and tall fibers is morphologically classified as A [other wrong options] [Discuss in forum] |
| Q6 ⇒ Which of the following viruses belong to family Hepadnaviridae? Hepatitis B virus [other wrong options] [Discuss in forum] |
| Q7 ⇒ The function of a viral capsid is all of the above [other wrong options] [Discuss in forum] |
| Q8 ⇒ Which of the following bacteriophage is said to have banal symmetry? all of these [other wrong options] [Discuss in forum] |
| Q9 ⇒ Which of the following viruses has not been associated with human cancer? Varicella-Zoster virus [other wrong options] [Discuss in forum] |
| Q10 ⇒ In cell culture, measles virus may lead to syncytium formation [other wrong options] [Discuss in forum] |
| Q11 ⇒ The viral DNA of the temperate phage, instead of taking over the functions of the cell's genes, is incorporated into the host DNA and becomes a prophage in the bacterial chromosome, acting as a gene. This happens in lysogeny [other wrong options] [Discuss in forum] |
| Q12 ⇒ The repressor protein, since the cell is resistant to lysis from externally infecting phage, is also called immunity repressor [other wrong options] [Discuss in forum] |
| Q13 ⇒ Which one is not useful in the treatment of viruses except penicillin [other wrong options] [Discuss in forum] |
| Q14 ⇒ The time from infection until lysis is called as latent period [other wrong options] [Discuss in forum] |
| Q15 ⇒ The extracellular phage number increases until a constant titer at the end of the multiplication cycle. This time interval is termed as rise period [other wrong options] [Discuss in forum] |
| Q16 ⇒ Usually viruses are separated into several large groups based primarily on nature of the host [other wrong options] [Discuss in forum] |
| Q17 ⇒ Plant viruses may be cultivated in all of these [other wrong options] [Discuss in forum] |
| Q18 ⇒ Which of the following viruses show/s transformation of infected cells? All of these [other wrong options] [Discuss in forum] |
| Q19 ⇒ Lysozyme (an endolysin) which will lyse the bacterial cell, releasing the mature virions is present in late genes [other wrong options] [Discuss in forum] |
| Q20 ⇒ Bacteriophages have been used widely in genetic research, since they are the smallest and simplest biological entities capable of self-replication [other wrong options] [Discuss in forum] |
