Students conduct their own research to discover and understand the methods designed by engineers and used by scientists to analyze or validate the molecular structure of DNA, proteins and enzymes, as well as basic information about gel electrophoresis and DNA identification. In this computer-based activity, students investigate particular molecular imaging technologies, such as x-ray, atomic force microscopy, transmission electron microscopy, and create short PowerPoint presentations that address key points. The presentations include their own explanations of the difference between molecular imaging and gel electrophoresis.
A memoir and history of the Institute of Agricultural Medicine at the University of Iowa, emphasizing its role in the development of the study and practice of occupational and environmental health and medicine for farmers their families and workers.
This Instructor’s Guide contains the brief outlines of Chapters 12-21 as found in Concepts of Biology, though some underwent revision. Also, instructors will find detailed outlines of the text for use in lecturing, as well as structured outlines that may be used by students to take notes while reading the chapter or during lecture. All outlines are derived from the OpenStax text. Additionally, study guides that contain a variety of questions are provided for students.
