文档介绍：实验十五 Using puter in biochemical research
Ⅰ. Introduction and theory
The puter has revolutionized the way we live. Not surprisingly, puter has also changed the way we do biochemical research. Your first encounter with puter in this laboratory will probably be while using an instrument that has puter to control its operation, to collect data, and to analyze data. All major pieces of scientific equipment including UV-VIS spectrometers, high-performance liquid chromatographs, gas chromatographs, nuclear ic resonance spectrometers, and DNA sequencers are now controlled puters. But your use of puter will not end in the lab. You will use puter to prepare each laboratory report including graphical analysis of experimental data. If puter is connected to the , you will greatly broaden its use to some of the following: (1) searching the biochemical literature for pertinent books and journal articles and (2) accessing biological databases that provide nucleic acid and protein sequences and protein structures.
puting in biochemistry
It is now possible for most students to purchase a puter system at low cost. Some mendations for specific hardware and software will be given here, but one must be aware that new products and important upgrades are continually being developed.
For word processing(writing lab reports), basic software programs including Microsoft Word and Word Perfect are most widely used. Software specialized for scientific writing is available but probably not necessary at this level. For many experiments that plete, you will need to present data in a spreadsheet or graphing or spreadsheet with graphing capability include Lotus, Excel, Sigmaplot, Quattropro, Kaleidagraph, and CricketCraph. Some graphs that you prepare from experimental data will be nonlinear. The mon example is a Michaelis-Menten graph from enzyme ics studies(substrate concentration vs. reaction rate). Since puters and programs have different methods for dealing with nonlinearity, it is probably
