Most NATs rely on decades-old methods that lyse pathogens and inactivate RNases with high concentrations of guanidinium salts. mount carmel school mohali facebook

"WebIt is known that RNase R contains an unusual, intrinsic RNA helicase activity that facilitates degradation of duplex RNA, but how it stimulates the nuclease activity has also been unclear. Here, we have made use of specifically designed substrates to compare the nuclease and helicase activities of RNase R. " - Nuclease rnase activity
