things throughout the body. There are many different types of diagnostic medical sonographers‚ including but not limited to‚ obsteric sonography‚ abdominal sonography‚ neurosonography‚ or breast sonography. Obsteric sonographers specialize in the imaging of the female reproductive system. The most common use of sonography in this job is examining the fetus of a pregnant woman to track the baby’s growth and health. This is the sonographer I wish to be. Although this is the most common sonographer‚

through a gel matrix toward a positive pole. Because the molecules have to move through small holes in the lattice bonds in the agarose gel‚ smaller molecules move much faster than larger molecules. Using ultraviolet imaging of the molecules’ movement and a formula that relates molecular weight to the speed of travel through the gel‚ scientists can determine the size of the molecules. Electrophoresis is essentially a sieving process. The larger the fragment of DNA‚ the more easily will it become

Scientific Paper on Diffusion 2 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the

This means that there are not as many imidazole bonded to the nickel ions as the histidine. SDS-Page separates molecules based on molecular weight therefore; this once again corresponds with the results. Since‚ the elution of 25mM imidazole produced a higher molecular weight it thus shows that the protein is still bonded to the nickel ion disputed through the small Rf
