The chapter describe the contributions of the following people: Griffith; Avery, McCary, and MacLeod; Hershey and Chase; Chargaff; Watson and Crick; Franklin; Meselson and Stahl; describe the structure of DNA; describe the process of DNA replication; include the following terms: antiparallel structure, DNA polymerase, leading strand, lagging strand, Okazaki fragments, DNA ligase, primer, primase, helicase, topoisomerase, single-strand binding proteins. | The Molecular Basis of Inheritance Chapter 16 Overview: Life’s Operating Instructions In 1953, James Watson and Francis Crick introduced an elegant double-helical model for the structure of deoxyribonucleic acid, or DNA DNA, the substance of inheritance, is the most celebrated molecule of our time Hereditary information is encoded in DNA and reproduced in all cells of the body This DNA program directs the development of biochemical, anatomical, physiological, and (to some extent) behavioral traits © 2011 Pearson Education, Inc. Figure Figure How was the structure of DNA determined? Concept : DNA is the genetic material Early in the 20th century, the identification of the molecules of inheritance loomed as a major challenge to biologists © 2011 Pearson Education, Inc. The Search for the Genetic Material: Scientific Inquiry When T. H. Morgan’s group showed that genes are located on chromosomes, the two components of chromosomes—DNA and protein—became candidates for the .
