Which method of entry is used by non-enveloped or 'naked' viruses to enter animal cells?
A
Entry via membrane fusion.
B
Entry via endocytosis.
C
Entry via exocytosis.
D
Entry via viral absorption.
Verified step by step guidance1
Understand the structure of non-enveloped or 'naked' viruses: These viruses lack a lipid membrane, which influences their method of entry into host cells.
Recognize that non-enveloped viruses cannot use membrane fusion for entry, as they do not have an envelope to fuse with the host cell membrane.
Learn about endocytosis: This is a process where the host cell engulfs the virus in a vesicle, allowing the virus to enter the cell. Non-enveloped viruses often use this method.
Differentiate between endocytosis and exocytosis: Exocytosis is the process of expelling materials from the cell, not a method of viral entry.
Consider viral absorption: This term generally refers to the initial attachment of the virus to the host cell surface, not the actual entry method.
