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.
This enzyme synthesizes a new DNA strand from an old DNA template and also works to repair the DNA in order to avoid mutations. DNA polymerase catalyzes the formation of the phosphodiester bond which makes up the backbone of DNA molecules.
