Material Detail

This site is a chapter of the larger site "DNA from the beginning". This section discusses non-coding regions of DNA in the eukaryotic genome. Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs) are transposable (transposons) which are found both between coding regions (intergenic) and within genes (exons). The chapter discusses in great detail the experiments which helped determine the existence of this material and how it was determined that these elements are often highly repetitive by using CoT curves (DNA concentration and time). The material is taught by explaining the experiments that resulted in our understanding of this subject. For all of the modules of the larger site, the science behind each concept is explained using animations, an image gallery, video interviews, problems, biographies, and links. There are three sections, Classical Genetics, Molecules of Genetics and Organization of Genetic Material. Key features are the clear explanations of classical experiments and the excellent photographs of researchers and their labs.
