About our authors William S. Klug is an Emeritus Professor of Biology at The College of New Jersey (formerly Trenton State College) in Ewing New Jersey where he served as Chair of the Biology Department for 17 years. He received his B. A. degree in Biology from Wabash College in Crawfordsville Indiana and his Ph. D. from Northwestern University in Evanston Illinois. Prior to coming to The College of New Jersey he was on the faculty of Wabash College where he first taught genetics as well as general biology and electron microscopy. His research interests have involved ultrastructural and molecular genetic studies of development utilizing oogenesis in Drosophila as a model system. He has taught the genetics course as well as the senior capstone seminar course in Human and Molecular Genetics to undergraduate biology majors for over four decades. He was the recipient in 2001 of the first annual teaching award given at The College of New Jersey granted to the faculty member who most challenges students to achieve high standards. He also received the 2004 Outstanding Professor Award from Sigma Pi International and in the same year he was nominated as the Educator of the Year an award given by the Research and Development Council of New Jersey. When not revising one of his textbooks immersed in the literature of genetics or trying to avoid double bogies Dr. Klug can sometimes be found paddling in the Gulf of Mexico or in Maine's Penobscot Bay. Michael R. Cummings is a Research Professor in the Department of Biological Chemical and Physical Sciences at Illinois Institute of Technology Chicago Illinois. For more than 25 years he was a faculty member in the Department of Biological Sciences and in the Department of Molecular Genetics at the University of Illinois at Chicago. He has also served on the faculties of Northwestern University and Florida State University. He received his B. A. from St. Mary's College in Winona Minnesota and his M. S. and Ph. D. from Northwestern University in Evanston Illinois. In addition to this text he has written textbooks in human genetics and general biology. His research interests center on the molecular organization and physical mapping of the heterochromatic regions of human acrocentric chromosomes. At the undergraduate level he teaches courses in molecular genetics human genetics and general biology and has received numerous awards for teaching excellence given by university faculty student organizations and graduating seniors. When not teaching or writing Dr. Cummings can often be found far offshore fishing for the one that got away. Charlotte A. Spencer is a retired Associate Professor from the Department of Oncology at the University of Alberta in Edmonton Alberta Canada. She has also served as a faculty member in the Department of Biochemistry at the University of Alberta. She received her B. Sc. in Microbiology from the University of British Columbia and her Ph. D. in Genetics from the University of Alberta followed by postdoctoral training at the Fred Hutchinson Cancer Research Center in Seattle Washington. Her research interests involve the regulation of RNA polymerase II transcription in cancer cells cells infected with DNA viruses and cells traversing the mitotic phase of the cell cycle. She has taught undergraduate and graduate courses in biochemistry genetics molecular biology and oncology. She has also written booklets in the Prentice Hall Exploring Biology series. When not writing and editing contributions to genetics textbooks Dr. Spencer works on her hazelnut farm and enjoys the peace and quiet of a remote Island off the west coast of British Columbia. Michael A. Palladino is Vice Provost for Graduate Studies former Dean of the School of Science and Professor of Biology at Monmouth University in West Long Branch New Jersey. He received his B. S. degree in Biology from The College of New Jersey and his Ph. D. in Anatomy and Cell Biology from the University of Virginia. For more than 15 years he directed a laboratory of undergraduate student researchers supported by external funding from the National Institutes of Health biopharma companies and other agencies. He and his undergraduates studied molecular mechanisms involved in innate immunity of mammalian male reproductive organs and genes involved in oxygen homeostasis and ischemic injury of the testis. He has taught a wide range of courses including genetics biotechnology endocrinology and cell and molecular biology. He has received several awards for research and teaching including the 2009 Young Andrologist Award of the American Society of Andrology the 2005 Distinguished Teacher Award from Monmouth University and the 2005 Caring Heart Award from the New Jersey Association for Biomedical Research. He is co-author of the undergraduate textbook Introduction to Biotechnology. He was Series Editor for the Benjamin Cummings Special Topics in Biology booklet series and author of the first
