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.
E. coli Primase Catalyzes Formation of RNA Primers for DNA Synthesis. As noted earlier, DNA polymerases can only elongate existing primer strands of DNA or RNA. The primers used during DNA replication in both prokaryotes and eukaryotes are short RNA molecules whose synthesis is catalyzed by the RNA polymerase primase.
