17. For a virus, what advantages and disadvantages does the lytic lifecycle have compared with the lysogenic lifecycle? A. The lytic lifecycle allows a virus to wait until conditions are optimal before reproducing but also gives the host cell more time to detect and fight the virus. B. The lytic lifecycle ensures that the virus won't be detected by the host cell but also kills the host and forces the virus to find a new host cell. C. The lytic lifecycle allows viruses to reproduce more quickly but also kills the host and forces the virus to find a new host cell. D. The lytic lifecycle allows viruses to reproduce when the host cell reproduces, spreading to its daughter cells, but also gives the host cell more time to detect and fight the virus. Mark for review (Will be highlighted on the review page)

Answer:

C. The lytic lifecycle allows viruses to reproduce more quickly but also kills the host and forces the virus to find a new host cell.

Explanation:

The lytic lifestyle of the viruses (e.g. bacteriophage) can be described through the next steps:

  • attachment and injection into the host cell (e.g.bacterial cell)
  • synthesis of the early virus proteins which break down host's DNA
  • virus uses host's machinery (for the replication, transcription and translation) to produce the rest of its proteins and to form new virus particles.
  • host cell burst and many new virus particles are released.

During the lysogenic cycle, virus does not kill the host. It integrated its DNA into host's genome and stays dormant until conditions are optimal for reproduction.
