DNA Polymerase I (or Pol I) is an enzyme that participates in the process of DNA replication.Discovered by Arthur Kornberg in 1956, it was the first known DNA polymerase (and, indeed, the first known of any kind of polymerase). It was initially characterized in E. coli and is ubiquitous in prokaryotes.rom Wikipedia, the free encyclopedia.

Definition of Total Expense Ratio Total expense ratio (TER) is the ratio between total fund costs and total fund assets. It provides information regarding total costs involved annually for investment funds.
The nifty thing about the expense ratio is that it wraps all these various costs and expenses into one number so that you don't have to do a lot of math. Currently the typical expense ratio for an actively managed mutual fund is about 1.5%, and that number has been going up lately. With an expense ratio of 1.5%, a mutual fund is cutting itself in on 1.5% of the total money in the fund every year. That's whether there's a good year or a bad year for the fund.
