Once T4 DNA Has Been Injected into Host Cells, All

question 24

Multiple Choice

Once T4 DNA has been injected into host cells, all of the following virus life cycle stages take place EXCEPT:

• B) T4 undergo lytic or lysogenic cycles depending on environmental factors.
• C) Late in the T4 life cycle, phage-encoded lysozymes lyse the host cell, releasing about 200 phage particles.
• D) T4 DNA undergoes rolling-circle replication generating a multigenome concatemer for packaging into viral heads.
• E) T4 capsid assembles automatically in a predetermined order from part encoded by phage genes.
