In T4 Phages,which of the Following Makes the Initial Contact

Question

In T4 phages,which of the following makes the initial contact with the appropriate receptor site?
A)Tail fiber
B)Base plate
C)Collar
D)Tail tube

Accepted Answer

The tail fiber of T4 phages is responsible for making the initial contact with the appropriate receptor site on the host cell. This interaction activates the injection process, which allows the phage DNA to enter the host cell and initiate the infection process. The base plate, collar, and tail tube are all important components of the phage tail, but they do not make direct contact with the host cell receptor site.
