Ultracentrifugation in the Undergraduate Curriculum

购买了一台新的超离心机、密度梯度成形器和带有紫外线监测器和条带记录仪的梯度分级器，并正在用于制备、分离和分析血浆、病毒、细菌和真核DNA，以及分离叶绿体膜系统、细胞核、染色质和其他亚细胞成分。在生物学入门课程中，超速离心法将作为课堂演示被纳入，其中讨论了半保守复制等概念。通过选定的中级课程，学生对乐器的接触是分阶段进行的，一些学生在高级荣誉研究项目中达到顶峰。这所大学捐赠的金额相当于这笔奖金。

A new ultracentrifuge, a density gradient former, and a gradient fractionator with ultraviolet monitor and strip chart recorder have been purchased and are being used to prepare, fractionate and analyze plasmic, viral, bacterial, and eukaryotic DNA, as well as to isolate chloroplast membrane systems, nuclei, chromatin, and other subcellular components. Ultracentrifugation is being incorporated as lecture- demonstrations in the introductory biology course, where concepts such as semi-conservative replication are discussed. Significant student contact with the instruments progress in stages through selected intermediate level courses, and culminate in senior honors research projects for some students. The university is contributing an amount equal to the award.
