“Denaturation of Proteins” Denaturation is a process in which proteins or nucleic acids lose the tertiary structure and secondary structure which is present in their native state‚ by application of some external stress or compound such as a strong acid or base‚ a concentrated inorganic salt‚ an organic solvent (e.g.‚ alcohol or chloroform)‚ or heat. If proteins in a living cell are denatured‚ this results in disruption of cell activity and possibly cell death. Denatured proteins can exhibit

Synthetic Fibers Industry Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general‚ syntheticfibers are created by forcing‚ usually through extrusion‚ fiber forming materials through holes (called spinnerets) into the air‚ forming a thread. Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Raw materials:

How does the amount of dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine
