Question
Which of the following is characteristic of the Influenza virus life cycle in a host cell?Question 4Select one:a.Viral glycoproteins attach to specific proteins on the host epithelial cell.b.The host cell takes in the virus by endocytosis .c.Viral RNA is replicated using host cell enzymes.d.The host cell makes viral proteins using mRNA.e.all of the above
Solution
The correct answer is e. All of the above.
Here's why:
a. Viral glycoproteins attach to specific proteins on the host epithelial cell: This is the first step in the influenza virus life cycle. The virus uses its glycoproteins to attach to the host cell.
b. The host cell takes in the virus by endocytosis: After attachment, the virus is taken into the host cell through a process called endocytosis.
c. Viral RNA is replicated using host cell enzymes: Once inside the host cell, the virus uses the host's enzymes to replicate its RNA.
d. The host cell makes viral proteins using mRNA: The viral RNA is then used as a template to make viral proteins. This process is called translation.
e. All of the above: Since all the statements a, b, c, and d are correct, the answer is e. All of the above.
