The structure was solved by molecular replacement (MR) using the yeast homolog of p180 (PDB code 4FYD) as a search model9. Although the primer/template and dNTP were omitted from the MR search model, there was clear electron density for the primer and template DNA strands in the initial ...

A "Red-Black Tree" is a self-balancing Binary Search Tree," with each node marked with a color (either Red or Black) and has additional operations defined on it to maintain "balance." Some typical applications of Red-black trees areTreeMapandTreeSetin Java. Even the C++ STL library h...
