Two enzymes are typically used for repairing DNA with sticky ends (see Figure 1) Polymerase: Polymerase fills in the missing bases for the strand, in the 5' to 3' direction. The resulting double-stranded DNA will be the same length as the initial longest DNA strand. Exonuclease: Exonuclease removes the 3' overhangs.Enzyme kinetics is an essential topic in undergraduate Biochemistry courses. A laboratory work that covers the principal basic concepts of enzyme kinetics in steady state is presented.

Either it is released back to enzyme and free substrate, with rate constant k-1, or else it goes on to make product, with rate constant k 2. In a steady state approximation, the enzyme substrate complex is consumed as soon as it is formed. Again, we don't know how much free enzyme there is. We don't know how much enzyme-substrate complex we have.
