Dengue Virus Quiz

What is the primary role of the envelope proteins on the dengue virus?

• To protect the RNA genome

• To bind to cell surface receptors

• To provide energy for the virus

• To replicate the viral RNA

Which process allows the dengue virus to enter a host cell?

• Receptor-mediated endocytosis

• Active transport

• Direct fusion with the cell membrane

• Passive diffusion

What is the function of the protease enzyme in the dengue virus life cycle?

• To synthesize viral RNA

• To activate other viral proteins

• To bind to the host cell

• To form the viral envelope

How does the dengue virus ensure the production of multiple copies of its RNA?

• By fusing with other viruses

• By using host cell DNA as a template

• By directly translating the RNA into proteins

• By forming a double helix with a negative-sense RNA strand

What happens to the dengue virus before it is released from the host cell?

• It loses its envelope proteins

• It fuses with the host cell nucleus

• It becomes mature after processing of pre-membrane proteins

• It disintegrates into smaller particles
