Fitting right into the equation is Erin Hills Golf Course in Hartford, Wisconsin, the site of the 2017 U.S. Open. Erin Hills has never held the U.S. Open, although it has held the U.S. Amateurs, the U.S. Women's Amateur Public Links and other tournaments as well.
DNA has two main biological functions (aside from being a very elegant looking macromolecule). Primarily, it serves to store/determine the biological characteristics of any living thing according to a very specific arrangement of molecular connections, as will be defined in a later section of this site.
What is the function of DNA polymerase I? Proofreads DNA. (about 20 at a time before it dissociates). It is a 5' to 3' DNA polymerase but also has 5' to 3' and 3' to 5' exonuclease activity to proof read and correct mismatches. It works with DNA:DNA as well as RNA:DNA. It is responsible to replacing Okazaki RNA fragments with DNA fragments.
