A virus with a monopartite genome is one whose genome is

  • A.made of both DNA and RNA
  • B.present in two identical copies
  • C.contained in a single molecule of nucleic acid
  • D.divided among several separate virus particles

Answer: C

Correct answer: contained in a single molecule of nucleic acid

A monopartite genome is one molecule; a segmented or multipartite one is divided among several. The distinction matters because segmented viruses can reassort - two strains infecting the same cell exchange whole segments - which is how influenza produces the abrupt antigenic shifts that cause pandemics, and which a monopartite virus cannot do.
