Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Describe gel electrophoresisExplain molecular and reproductive cloningDescribe uses of biotechnology in medicine and agriculture
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Biodiesel from plant oils could be the fuel of the future, but the low quality of certain plant oils means that getting there will take some engineering. So, researchers are turning to genetics for a solution. They’ve developed a transgenic soybean line that could dramatically increase biodiesel performance. Biodiesel performance relies on the fatty acid composition of the source oil. On average, soybean oil is only 25% oleic acid, which is a desirable monounsaturated fatty acid, and 13% palmitic acid, an undesirable saturated fatty acid. This fatty acid profile negatively affects biodiesel’s rate of nitrogen oxide emission and freezing point. Through metabolic engineering, the soybean genes FAD2-1 and FatB were down-regulated using RNA interference technology to increase the production of oleic acid to nearly 95% and decrease the production of palmitic acid to less than 3%, with no detectable differences in the fatty acid chemical structure between modified and standard soybean lines..."
