John has just been unknowing exposed to HIV-1 after sharing a needle with his friend who is HIV positive. Place in order the progressive events of HIV virus infiltration to replication: Newly cleaved viral proteins migrate to the cell membrane of infected cell Chemokine coreceptors on CD+4 ligate glycoproteins found on the virus allowing for internalization of virus into CD4+ cell Viral RNA and reverse transcriptase are deposited into CD4+ cell Integrated viral DNA is transcribed to mRNA and translated to polyprotein RNA is changed to DNA via reverse transcriptase and integrated into the CD4+ cell DNA by integrase creating the provirus
