BIOCHEMISTRY          In the scientific diary article deoxyribonucleic acid Aptamers Selected against the HIV-1 ribonuclease H Display in Antiviral Activity from the Biochemistry diary the researchers were talking ab step up an restrictor of the ribonuclease H activity on RNA-DNA hybrids. Since they know that a vaccination against HIV-1 is still a want goal. They want to make an subordinateor that will be more affectional at blocking the viral replication and thus comfortably the onset and progression of the HIV-1 virus. The article states that new disallowors have been launch using the SELEX method that means 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 seize oligonucleotide sequences, which atomic number 18 emerging as a class of molecules that play off antibod ies. Many of the oligonucleotides selectively inhibit the DNA polymerase actively. Most of the compounds inhibiting the HIV-1 mold by inhibiting the DNA polymerase affaire on the RT. Some of these compounds are AZT, ddI, ddC, and nevirapine.

        In the try that they carried out they found that the molecules that they chose in this experiment do not tract features with the DNA aptamers previously detached 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 likeness with RNA aptamers. But this is judge since the RNA chains of the correspo! nding sequence do not usually adopt the geometry take by the DNA. In destruction the results of the scientists that carried out the experiment showed that the oligonucleotides used were powerful inhibitors of the HIV-1 virus.
