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.
DNA is the genetic material, and genes are made of DNA. DNA therefore has two essential functions: replication and expression. 1  Replication means that the DNA, with all its genes, must be copied every time a cell divides.  Expression means that the genes on DNA must control characteristics.
