Part C: The Big Picture – In this part, you will use the information from Part A and Part B so answer questions. 1. When you were creating the complimentary DNA strands, what bases (letters) paired together? Were there any bases that could pair with more than one base (letter)? 2. Using the following DNA sequence, ATTACGCATATG, what would the sequence of the complimentary strand be? 3. Could DNA be replicated without the use of enzymes? Explain your answer by giving specific examples. 4. If you replicate on strand of DNA, how many do you end up with? Are the strands identical to the original or different? How do you know?

Show how you arrived at your answers_ c) If Chargaff's rule-that the amount of A equals the amount of T and the amount of C equals the amount of G ~is valid, then hypothetically we could extrapolate this to the combined DNA of all species on Earth (like one huge Earth genome) . To see whether the data in the table support this hypothesis, calculate the average percentage for each base in your completed table by averaging the values in each column: Does Chargaff's equivalence rule still hold true?

BICD100 HW6 Prokaryotic Genetics Question 1. You are interested in three genes in bacteriophage. The recessive mutant alleles cause plaque phenotypes that were creatively named fuzzy, shaky, and purple. Another lab published the following map of the three genes: fuzzy shaky 2.9 17.4 purple To verify the published map, you cross a purple shaky phage strain with a fuzzy phage strain by co- infecting E. coli at a high multiplicity of infection (every bacterium infected with both types of phage). You plate the resulting lysate and analyze the phenotypes of the plaques caused by the progeny phage. a. State the genotypes of the two parent phage strains: b. List all eight of the possible phenotypes that could result from this cross. If 400 phage plaques were examined from this cross, how many plaques of each of the eight phenotypic classes would you expect?

Question1

The Evidence: 1953 1953: Rosalind Franklin, working in Maurice Wilkins' lab, determines the spatial relationships of the helical backbone, that there are two forms of DNA, and that the A form is antiparallel. Using X-ray crystallography, she shows the overall structure of DNA. 1953: James Watson and Francis Crick discover the molecular structure of DNA. QUESTIONS 1. What should you conclude at this time? 2. What was the contribution of Watson and Crick? DNA Structure DNA is composed of a double chain of four alternating nucleotides. Each nucleotide contains a sugar (deoxyribose), a phosphate group, and a nitrogenous base. There are only four different nitrogenous bases in DNA: adenine, thymine, guanine, and cytosine. Figures 7.1 and 7.2 show the structure of each of these bases. These four nucleotides differ only in the nitrogenous base.
