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.
After a base is added, the DNA helix reforms, and the RNA chain is separated from the DNA template strand. Similar to a DNA polymerase, a RNA polymerase catalyzes the formation of the phosphodiester bonds between bases, but these bases are ribonucleic acids rather than deoxyribonucleic acids. They polymerize the new strand in the 5' terminus to 3' direction, like DNA polymerase.
