RECOMBINANT-DNA METHODOLOGY
... Cutting with restriction endonucleases is very useful for moving specific pieces of DNA around from place to place. It’s also a useful way to name pieces of DNA. For example, a piece of DNA that is cut from a bigger piece of DNA is often named by size and given a surname that corresponds to the two ...

CHAPTER 4: Enzyme Structure
... Up to the optimum temperature the rate increases geometrically with temperature (i.e. it's a curve, not a straight line). The rate increases because the enzyme and substrate molecules both have more kinetic energy and so collide more often, and also because more molecules have sufficient energy to o ...
