QUESTION 3 A _______ uses the lytic cycle to begin the immediate manufacture of new phages in the host cells. temperate phage virulent phage bacteria eukaryotic cell QUESTION 4 A bacteriophage that is physically integrated into the host chromosome is called a _______. heteroduplex envelope phage plaque prophage
Sri K.
1. Lytic phages lyse their host cells, whereas temperate phages either lyse their host or integrate their DNA into the host cell’s genome. Prophage DNA often codes for gene products that confer new properties on the host. Filamentous single-stranded DNA phages are extruded from the host cells without killing the cell. How can a productive phage infection not kill a host cell?
Adi S.
The phages T4 (lytic) and lambda (temperate) share all of the following characteristics EXCEPT: A. causing productive infections that involve host cell lysis. B. existing as a prophage. C. having a DNA genome. D. Attaching via a receptor on the bacterial cell surface. E. injecting their genome into the host cell. F. having a nucleocapsid.
