In biochemistry, turnover is a term that refers to the rate at which a compound is produced and subsequently degraded. Within the cell, many compounds are continuously being synthesized and degraded, although at a range of different rates. In a typical cell, how would the turnover rates for DNA, mRNA, and protein be expected to differ from largest to smallest?
