Final answer:
HIV (Human Immunodeficiency Virus) functions similarly to the vesicle fusion process during its entry into host cells.
Step-by-step explanation:
Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, HIV can lead to the disease Acquired Immunodeficiency Syndrome (AIDS).
HIV (Human Immunodeficiency Virus), which is a retrovirus, utilizes a fusion process similar to vesicle fusion during its entry into host cells. The fusion process of HIV involves the interaction of the viral envelope glycoprotein with the host cell receptor and co-receptor, leading to membrane fusion.
