Arrange the steps in the order that they occur during viral infection and replication. a. Reverse transcriptase synthesizes DNA complementary to viral RNA.
b. Viral proteins assemble around viral RNA and reverse transcriptase.
c. New viruses acquire an envelope as they exit the host cell by exocytosis.
d. Viral genes are transcribed, and translation produces viral proteins.
e. HIV envelope proteins bind to host cell receptor and coreceptor.
f. Double-stranded DNA is incorporated into host cell's DNA.
g. Host cell engulfs HIV particle, and enzymes remove viral protein coat.

Explanation:

The human immunodeficiency virus (HIV) is a retrovirus (genus Lentivirus) whose genetic material is a positive-sense single-stranded RNA. HIV is known to infect HIVcells of the human immune system such as, for example, macrophages, T cells, dendritic cells, etc., eventually leading to the acquired immunodeficiency syndrome (AIDS). Within host cells, the HIV genome is reverse transcribed into DNA by using a specific enzyme called reverse transcriptase. Then, this DNA is integrated into the genome of the host cell, replicating when the host cell replicates. Moreover, the integrated HIV genome can also be transcribed to produce RNA and proteins capable of infecting new cells.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
