BIOCHEMISTRY          In the scientific diary article deoxyribonucleic acid Aptamers Selected against the HIV-1 ribonuclease H Display in Antiviral Activity from the Biochemistry journal the researchers were talking ab bulge an restrictor of the ribonuclease H activity on RNA-DNA hybrids. Since they know that a vaccination against HIV-1 is still a hanker goal. They want to make an reduceor that will be more emotive at blocking the viral replication and thus easy the onset and progression of the HIV-1 virus. The article states that new conquerors have been abide using the SELEX method that means systematic evolution of ligands by exponential enrichment. In the article the scientists apply SELEX to discriminate ligands that inhibit ribonuclease H activity associated with the HIV-1 RT. With SELEX scientists have been able to specify oligonucleotide sequences, which atomic number 18 emerging as a class of molecules that play off antibodies. 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 divide 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 proportion with RNA aptamers. But this is judge since the RNA chains of the uniform sequence do not usually adopt the ! geometry espouse 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.
