The genetic material for some animal and plant viruses is RNA rather than DNA. Although some RNA viruses never have their information transcribed into a DNA molecule, many animal RNA vtruses-specifically, the retroviruses the HIV virus, for example- are transcribed by viral RNA-dependent DNA polymerase, the so-called reverse transcriptase, to produce a double-stranded DNA copy of their RNA genome - Harper 28th307Table Chatterjea Shinde7th261iEnzymes used in recombinant DNA technologyNameReactionFunctionRestriction endonucleaseCut DNA at specific DNA sequence within the moleculeChimical knife in recombinant DNA technologyReverse transcriptaseSynthesizes DNA from RNA templateSynthesizes c-DNA from m-RNASt nucleaseDegrades ss-DNARemoval of hairpin in DNA synthesis of c-DNADNA LigaseCatalyzes bond between DNA moleculesjoining of DNA moleculesDNA Polymerase 1Synthesizes ds-DNA from ss-DNASynthesis of ds c-DNA: nick translationBAL3 1 nucleaseDegrades both 3 and 5 ends of DNAProgressive shortening of DNA moleculesAlkaline phosphataseDephosphoryiates 5 ends of RNA and DNARemoval of 5 -P04 Groups to kinase labeling to prevent self Ligation
