Provirus

In animal viruses, newly made ----is used to synthesize viral proteins.

RNA

Which of the following is a multinucleated mass of cells due to the cytopathic effect of viral infection?

Syncytium

What name is given to a phage "type" which can incorporate itself into the host genome as a lysogenic prophage?

Temperate

-----phages enter the prophage state, -----while phages burst the host cell.

Temperate lytic

-----is when a phage transfers genes between bacteria.

Transduction

Both naked and complex viruses are released from host cells via lysis once mature.

True

Two ways in which newly assembled viruses are released from host cells are through (exocytosis) by enveloped viruses, and through (rupture) by naked viruses.

budding Blank 2: lysis or cell lysis

Virus-induced damage to the cell that alters its microscopic appearance is termed ______.

budding ,lysis

The process of -------, Correct Unavailable, a type of penetration, occurs when viruses are taken into the cell followed by engulfment in a vacuole or vesicle.

endocytosis

Viral spikes insert into the host cell membrane as the virion is released from the cell.

false

The -----, Correct Unavailable range defines the limitations of the type of cell that a virus can invade.

host

Viruses -----that are lead to cancer in infected hosts.

oncogenic

Viruses that are lead to cancer in infected hosts.
