Question

The protein coat that surrounds the genetic material of the T2 phage is termed the:______

A) Capsid.
B) Envelope.
C) Nucleoid.
D) Membrane.
E) Cell wall.

Answer 1

Th correct answer is A. Capsid

Step-by-step explanation:

T-2 phage is a bacteriophage which is virulent to E.coli which means T2 phage infects E.coli. The genetic material of T2 phage is linear DNA which is double-stranded. The genetic material of T2 phage is enclosed in a protein coat which is called capsid.

This capsid protects the genetic material of bacteriophage by any enzymatic digestion, helps the virus to attach the host cell and helps the virion to penetrate the cell membrane of the host cell and inject its genetic material in the host cell. Therefore capsid is the correct answer.
