DNA Replication Enzymes: Roles and Worked Examples
A typical diploid human cell preparing to divide copies roughly six billion base pairs of nuclear DNA. Each daughter cell needs a complete set. An error at every thousandth base would leave extensive damage, while the illustrative final error rate used here is about one per billion after correction.
Enzyme Kinetics: Km, Vmax and Inhibition
Pour hydrogen peroxide on the kitchen counter and it sits there, decomposing so slowly that a sealed bottle lasts for months. Add a small piece of potato to a supervised laboratory peroxide assay and it foams quickly. The chemistry is identical in both places: peroxide breaking down into water and o
