in the design of selective inhibitors of the human immunodeficiency virus ( hiv ) , the etiologic agent of aids , various steps of the virus replicative cycle could be envisaged as targets , i.e . virus adsorption to its cellular receptor ( or another early event in virus replication such as penetration or uncoating ) , transcription of the viral rna genome to proviral dna ( reverse transcription ) , trans-activation of viral mrna transcription and translation , and , finally , virus release ( `` '' budding '' '' , or another late event in virus replication such as the assembly process ) .
