Q927

Phages attach themselves to the host tissue through

A.
Base
B.
Head end
C.
Tail end
Answer
D.
Protein coat

Answer: Option C

Solution

Answer: Option C
Solution:
Phages attach themselves to the host tissue through the tail end.
The tail of the bacteriophage includes the tail sheath, base plate and tail fibers, which are made of different proteins. The long tail fibers are used by the bacteriophage to attach itself to the bacterium and the virus then inserts its genetic material inside of the host cell to begin the replication process.
The phage tail is a complex, multiprotein structure that mediates attachment, digestion, and penetration of the cell wall and genome ejection.
