T4 rnase h
WebRibonuclease H (RNase H) is an endoribonuclease that specifically degrades the RNA strand of an RNA-DNA hybrid to produce 5´ phosphate-terminated oligoribonucleotides and single-stranded DNA. Applications Removal of mRNA during second-strand cDNA synthesis. Removal of poly (A) sequences from mRNA in the presence of oligo (dT). WebRNase H activity of reverse transcriptases on cDNA synthesis. To improve cDNA synthesis, the RNase H activity of reverse transcriptases has been reduced or diminished by introducing mutations into the RNase H domain of the enzyme. Such mutations often result in higher yield and synthesis of longer cDNAs ( Figure 3) [2]. Figure 3.
