T-Even Phages

Question

T-even phages
A)include the poxviruses.
B)infect Escherichia coli cells.
C)enter host cells by engulfment.
D)have helical capsids.
E)All of these choices are correct.

Accepted Answer

T-even phages are a group of bacteriophages that infect E. coli cells. They have complex, polyhedral heads and contractile tails that allow them to inject their genetic material into the host cell. Their genome is linear and double-stranded DNA. They are not poxviruses, do not enter host cells by engulfment, and do not have helical capsids.
