spreading of a light pulse as it travels down a fiber when light pulses launched close together(high data rates) spread too much and result in errors and a loss of information. The spectral width determines the number of different wavelengths that are emitted from LED or laser. One way to reduce chromatic dispersion is to narrow the spectral width of the transmitter. Chromatic dispersion can be compensated for with the use of dispersion-shifted fiber (DSF). Laser has a more narrow spectral width

are present in a protein‚ in this case gluten. Introduction: Proteins are large biological molecules that are made up of amino acids. They serve as building blocks that form organic structures such as tendons‚ muscle‚ and cartilage. Enzymes - biological catalysts that allow important chemical reactions to occur in our body - are also made up of proteins. Thus‚ proteins play a fundamental role in the processes of life. [1] Protein purification is basically isolating a protein from complex mixtures

AP Bio Ras Protein Paper The Ras proteins are a family of proteins that belong to a class of proteins called the small GTPase’s. They belong to a large super-family of proteins known as "low-molecular weight G-proteins". They are used to transmit signals throughout a cell using transduction. They strengthen the signals conveyed by linking them to a chemically irreversible process such as the cleavage of GTP. Ras proteins are usually in the “off” state where the GDP is bound to the site. However

EXPERIMENT NO. 15 PROTEIN CHARACTERIZATION BY ELECTROPHORESIS Abstract The molecular weights of protein extracts were assessed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Two sets of four protein samples‚ standard bovine serum albumin (BSA)‚ invertase‚ egg albumin‚ and casein‚ were prepared; one set containing β-mercaptoethanol (BME) while the other did not. These were then analyzed through SDS-PAGE with 12.5% resolving gel‚ prepared using 2 M Tris-HCl at pH 8
