Question

The conditions for a virus to attack a host cell is

• A. The virus must have the DNA or RNA key sequence to enter the host cell.
• B. The virus must have the enzymes to cause the host cell to burst so that the host cell may be used as raw materials.
• C. The virus must have the proper enzyme to puncture the membrane of the host cell.
• D. The virus must have a particular shape that will match up with the proteins on the surface of the host cell.
• E. The viral DNA or RNA must have sequence that is recognised by the ribosomes of the host cell.

Answer 1

The correct option is D The virus must have a particular shape that will match up with the proteins on the surface of the host cell.

• Viruses are organisms that survive in living hosts.
• These are actually biological agents that produce identical copies of its strain inside the host cell and leads to infections.
• Viruses are found in the environment and upon the presence of a host cell will try to attack.
• However, in order to attack, the virus must attach to a host cell which can be achieved when receptors on the viral envelope become connected to complementary receptor proteins of the target cells membrane.
• Thus, the correct answer is option D.
