0 13 The Molecular Basis of Inheritance 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 (DNA replication) Figure 13.1 Concept 13.1: DNA is the genetic material Early in the 20th century, the identification of the molecules of inheritance loomed as a major challenge to biologists The Search for the Genetic Material: Scientific Inquiry

Chapter 16: The Molecular Basis of Inheritance Overview: Life?s Operating Instructions Watson and Crick introduced the double-helical model for the structure of DNA DNA is the substance of inheritance encoded in chemical language of DNA and reproduced in all the cells of your body it is DNA that directs the development of many different types of traits Concept 16.1: DNA is the genetic material The Search for the Genetic Material: Scientific Inquiry the role of DNA in heredity was first worked out by studying bacteria and the viruses that infect them Evidence That DNA Can Transform Bacteria Griffith worked with a pathogenic and nonpathogenic strain

Ch 16 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because a. proteins have a greater variety of three-dimensional forms than does DNA. b. proteins have two different levels of structural organization; DNA has four. c. proteins are made of 20 amino acids and DNA is made of four nucleotides. d. Only A and C are correct. e. A, B, and C are correct. ____ 2. In his transformation experiments, Griffith observed that a.

DNA Replication INDIVIDUAL: List the enzymes/proteins involved in DNA replication and describe their role. What is a nucleotide composed of? What makes up the backbone of DNA? What are the DNA bases? Tell which are purines and pyrimidenes. Which bases pair together? What holds them together? GROUP: Replication of DNA follows the __________________________________model. Explain this model, in addition to the other two which DNA replication does not follow. A DNA strand has the following bases: A A G C C A. What are the bases on its complimentary strand? During DNA replication, nucleotides are brought in as______________. Why is this? (Bubble the right answer)

Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________ Period___________ Chapter 16: The Molecular Basis of Inheritance Concept 16.1 DNA is the genetic material 1. What are the two chemical components of chromosomes? DNA and protein 2. Why did researchers originally think that protein was the genetic material? Until the 1940s, the case for proteins seemed stronger, especially since biochemists had identified them as a class of macromolecules with great heterogeneity and specificity of function, essential requirements for the hereditary material. Moreover, little was known about nucleic acids, whose physical and chemical properties seemed far too uniform to account for
