Page 1 AP Biology: 2013 Exam Review AP BIOLOGY EXAM REVIEW GUIDE ?The price of success is hard work, dedication to the job at hand, and the determination that whether we win or lose, we have applied the best of ourselves to the task at hand.? Page 2 AP Biology: 2013 Exam Review CONCEPT 1 - BIOCHEMISTRY 1. CHNOPS- most common elements in all living matter 2. Bonds- ionic (transfer electrons), covalent (sharing- polar/unequal sharing and non-polar/equal sharing), hydrogen (weak bonds between hydrogen and negatively charged items), hydrophobic interactions (how non-polar compounds congregate together- lipids) 3. pH a. acid-base/ 0-14, # of H ions determines scale; logarithmic- pH 3 = 10-3 = 1/1000

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

AP Biology: DNA Replication Lab You will use simulations to demonstrate the structure and replication of DNA in this laboratory exercise. As you have studied, the genetic information for living organisms is stored in the structure of deoxyribose nucleic acid (DNA). Our DNA molecules carry the genetic code for inherited characteristics in the triplet-coded sequences of its nitrogen bases. Each time a cell divides, its DNA is precisely duplicated (DNA replication) so that the DNA of the cells formed is identical to that of the original cell.

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)

Chapter 16 The Molecular Basis of Inheritance Essay questions will be on Feulgen, Griffith experiement, Hershey and Chase, Chargoff, Watson and Crick, Tatum Beadle Experiment Overview: Your genetic material is contained in: 1. 46 chromsomes from mom and dad 2. Mitochondrial DNA from mom Nucleic acids - Unique from all other molecules in that they can direct their own replication. 16.1 DNA is the genetic material A. The Search for Genetic Material: Scientific Inquiry Initially, Genes were noted to be on chromosomes (b/c of work by Morgan an d Mendel) ? so people didn?t know if they were on the proteins or on the DNA. 1. Frederick Griffith (figure 16.2)? Showed evidence that DNA (not protein) can transform bacteria Background:

Molecular Biology Unit Exam Question 1 Consider the following origin of replication that is found on a chromosome. The sequence of region 1 is shown below. Region 1: 5??CTGACTGACA?3? 3??GACTGACTGT?5? 3? 5? 5? 3? Region 1 top ? ori bottom ? a) Within Region 1, which strand will be the template for leading strand synthesis, the top or the bottom? b) If we assume that a lagging strand fragment is made from region 1, what will be its sequence? c) You examine DNA replication in an E. coli mutant, which has a partially defective DNA polymerase. In vitro experiments using the mutant DNA polymerase gives an error rate of 10-3, as compared to the expected error
