BIOCHEMISTRY          In the scientific daybook term deoxyribonucleic acid Aptamers Selected against the HIV-1 ribonuclease H Display in Antiviral Activity from the Biochemistry journal the researchers were talking ab forbidden an restrictor of the ribonuclease H action on RNA-DNA hybrids. Since they know that a vaccination against HIV-1 is still a pertinacious goal. They want to make an forbidor that get out be more affectional at blocking the viral replication and thus good the onset and progression of the HIV-1 virus. The expression states that new subdueors have been rear using the SELEX method that substance systematic evolution of ligands by exponential enrichment. In the article the scientists use SELEX to discriminate ligands that inhibit ribonuclease H activity associated with the HIV-1 RT. With SELEX scientists have been able to attach oligonucleotide sequences, which atomic number 18 emerging as a class of molecules that play score antibodies. Many of the oligonucleotides selectively inhibit the DNA polymerase actively. Most of the compounds inhibiting the HIV-1 moulding by inhibiting the DNA polymerase run short on the RT. Some of these compounds be AZT, ddI, ddC, and nevirapine.

        In the try that they carried out they found that the molecules that they chose in this essay do non packet features with the DNA aptamers previously quarantined against the HIV-1 RT. The aptamers were predicted to form pseudoknots, but they did not. The selected DNA ligands shared little or no structural resemblance with RNA aptamers. But this is judge since the RNA chains of the said(prenominal) sequence do not usually adopt the geometry espouse by the DNA. In closing the results of the scientists that carried out the experiment showed that the oligonucleotides used were powerful inhibitors of the HIV-1 virus.
