Debris from Total Hip Replacement or Hip Resurfacing Procedures. After total hip replacement or hip resurfacing, particle debris from the cup, ball or ball covering can lead to complications and implant failure. As the implant recipient moves, the surfaces of the components rub against each other. The friction and abrasive wear between the components produces debris.
Reverse transcriptase is the viral enzyme responsible for making a DNA copy of the RNA genome from a retrovirus. As such, it is technically known as an RNA-dependent DNA polymerase. This is opposite to the usual flow of genetic information from DNA to RNA to protein.
Reverse Transcriptases. Reverse transcriptase is a common name for an enzyme that functions as a RNA-dependent DNA polymerase. They are encoded by retroviruses, where they copy the viral RNA genome into DNA prior to its integration into host cells. DNA polymerase activity: In the retroviral life cycle, reverse transcriptase copies only RNA, but, as used in the laboratory, it will transcribe both single-stranded RNA and single-stranded DNA templates with essentially equivalent efficiency. 2  In both cases, an RNA or DNA primer is required to initiate synthesis.
