8. You are studying the biochemical pathway of purrine production. (Purrines are a type of nucleotide used in feline DNA, a little different than the purines in the DNA of lower species like humans.) You have several mutants that cannot make purrine, and you do complementation tests to see how many different genes you've identified. Here are your data: mutant 1 2 3 7 8 9. 1 2 4 6. 7 8 + a) What is the deal with mutant #1 and why must you ignore it when figuring out complementation groups? b) For the rest of the problem, ignore mutant #1. List your complementation groups. Hint: every single one of your mutants (except #1 of course) must be in a group. c) How many genes did you, therefore, identify?

4. You can carry out matings between an Hfr and F−strain by mixing the two cell types in a small patch ona plate and then replica plating to selective medium.This methodology was used to screen hundreds of different cells for a recombination-deficient recA− mutant. Why is this an assay for RecA function? Wouldyou be screening for a recA− mutation in the F− or Hfrstrain using this protocol? Explain.
4. A recent estimate of the rate of base substitutions atSNP loci is about 1 × 10−8 per nucleotide pair pergamete.a. Based on this estimate, about how many de novomutations (that is, mutations not found in the genomes of your parents) are present in your own genome?b. Where and when did these de novo mutations inyour genome most likely occur?
1. The first genetic test developed for this disease took advantage of a large family of over 2,000 individuals who lived along Lake Maracaibo in Venezuela. These family members, some with and some without Huntington’s disease, could all trace their ancestry to a single female who settled in the region a number of generations ago.Genomic DNA from family members with and without Huntington’s disease was cut with a set of enzymes that make reproducible cuts at known DNA sequences. These DNA fragments were run on a DNA gel to see which fragments correlated with the presence of Huntington’s disease. a) How might the large number (over 2,000) of family members who have a common ancestor who suffered from Huntington’s disease make it easy to narrow down the gene location of the Huntington’s locus (compared to doing the same experiment with a small family descended from a Huntington’s sufferer)?
1. In his transformation experiments, what did Griffith observe? a. Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form b. Mixing a heat-killed nonpathogenic strain of bacteria with a living pathogenic strain makes the pathogenic strain nonpathogenic c. Mutant mice were resistant to bacterial infections. d. Infecting mice with nonpathogenic strains of bacteria makes them resistant to pathogenic strains

1. Through observing the sequence of events (A → B → C → D) found below, describe how reproductive cloning is made possible. Your response should consist of 3—5 complete sentences. SENTENCE STARTER: The process of cloning may look quite tricky, but it can actually be broken down into 4 individual steps. In step A, the cells of the organism we want to be cloned are isolated and the… 2. What is an ADVANTAGE of engaging in cloning practices similar to the one highlighted above? What reason might a farmer, livestock owner, or someone else use as justification for cloning? 3. What is a DISADVANTAGE (or potential drawback) of cloning plants, livestock, or pets?
1) Recombinant DNA technology and selective breeding are 2 techniques that seek to produce desirable traits within an organism, yet they do so in very different ways. How do the methods of each process differ? What technique would more reliable in producing the desired outcome? Why?
1. Methods of gene therapy 2. Explain Small RNAs and long non coding RNA. 3.what is name of the technique that would help a person who inherited LFS to have a child without the defective allele? 4 .Describe the main technique for amplifying a segment of DNA (like the one you suspect is involved in Lee’s cancer) from a complex mixture of genomic DNA. Remember that the entire human genome sequence is known. (Hint: This is a technique that is commonly used by laboratories that do genetic testing and various other applications of molecular biology.) 5. If Dr. Aikenhed wanted to see if there was mutation within the protein-coding sequence of the gene implicated in this disorder (as opposed to mutations afecting regulatory elements), what technique involving dideoxynucleotides could be used? Briefy describe this technique.
In DNA-hybridization experiments on six species of plants in the genus Vicia, DNA was isolated from each of the six species, denatured by heating, and sheared into small fragments (W. Y. Chooi. 1971. Genetics 68:213–230). In one experiment, DNA from each species and from E. coli was allowed to renature. The graph shows the results of this renaturation experiment. Q. Notice that, for the Vicia species, the rate of renaturation is much faster in the first hour and then slows down. What might cause this initial rapid renaturation and the subsequent slowdown?
