  1. 3. This is the largest virus causing infection in humans
  2. 4. Release of daughter virions from the infected cells is also termed as
  3. 5. This is recognized as smallest human virus
  4. 9. These are highly infectious proteins that cause slow and deadly diseases in humans
  5. 11. This is the term used for describing double stranded RNA viruses that have both positive and negative sense RNA
  6. 12. The viral structure consisting of genome and protein shell surrounding it is called as
  7. 13. These glycoprotein projections embedded in to the viral envelope are called as
  8. 14. These small infectious particle infect plants and consists of only nucleic acid and lack protein coat
  9. 15. Rabies virus affects neurons by binding through these receptors

  1. 1. These defective virus-like particles have capsid proteins surrounding host cell DNA instead of Viral nucleic acid
  2. 2. Most of the naked viruses have this type of symmetry characterized by presence of 12 vertices and 20 facets
  3. 3. The portion of phage genome that gets integrated with bacterial DNA is called as
  4. 6. Protein shell surrounding the genome is composed of protein subunits which are called as
  5. 7. Most of the enveloped viruses have this type of symmetry
  6. 8. Hepatitis D virus always requires the help of the hepatitis B virus for its replication. Hence Hepatitis B virus is termed as... virus
  7. 10. This phenomenon of genetic variation that results from mixing of genetic segments of two different viruses is called as
  8. 14. An intact virus particle is called as
