You have isolated 8 mutants in yeast that fail to grow on minimal media plates but do grow when they
are supplemented with Arginine. You know that Arginine is synthesized in a biochemical pathway within
wild-type yeast, but you do not know how many gene products it takes for the pathway. You have all of the
lines as both a and a cells and mate each strain to each other in pairwise crosses and plate them on minimal
media to see if they grow. You obtain the following results with (+) representing growth, and (-) indicating
no growth:

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?
You are interested in studying resistance to heavy metals and have selected the yeast Saccharomyces cerevisea to conduct your studies. You have recovered a deletion mutant that does not tolerate high concentrations of zinc (grows poorly in zinc containing media ) and have designated the mutant pgz-1 (for poor growth in zinc ). (a) What is the advantage to the type of mutant used in this work? What class of mutagen was likely use to generate pgz-1?
( b) Do you expect the PGZ gene to be expressed in your mutant? Explain.

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. Can you explain why the E. coli DNA renatures at a much faster rate than does DNA from any of the Vicia species?arrow_forwardA 19 year old female patient is diagnosed with chronic myelogenous leukemia. Karyotype analysis shows that the leukemic cells of this patient are heterozygous for a reciprocal translocation involving chromosomes 9 and 22. However, none of the normal, nonleukemic cells of this patient contain the translocation. a) Describe a molecular test to determine if chemotherapy given to the patient described would be completely succesful. (That is, devise a method to make sure that the patient's blood would be free of leukemic cells.) Be as specific as possible.arrow_forwardYou receive four strains of yeast in the mail, and the accompanying instructions state that each strain contains a single copy of transgene A. You grow the four strains and determine that only three strains express the protein product of transgene A. Further analysis reveals that transgene A is located at a different position in the yeast genome in each of the four strains. Provide a hypothesis to explain this result.arrow_forward
- The period gene of Drosophila melanogaster encodes for a stretch of Thr-Gly repeated in tandem. In natural populations, the three most common alleles encode for 17, 20 and 23 Thr-Gly repeats. The amplification by PCR of the allele encoding for 20 Thr-Gly repeats produces a fragment of 320 bp. Using the same set of primers, what is the size expected when amplifying the 17 Thr-Gly allele? 317 303 314 302 In a certain species of plant loci A, B and C have an additive effect on the colour of the flower. Alleles A, B, and C are dominant and alleles a, b and c are recessive. Knowing that a plant with genotype AAbbCc has a pink flower, which genotype, among the ones listed below, will produce the same phenotype? Aabbcc. aabbcc. AaBbCc. AABBCc. In pea plants, tall (T) is dominant to dwarf (t) and yellow (Y) is dominant to green (y). In a cross of true-breeding tall yellow peas x dwarf green…arrow_forwardA paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.arrow_forwardEC4.

- When the S.cerevisiae genome was sequenced and surveyed for possible genes, only about 40% of those genes had been previously identified in forward genetic screens. This left about 60% of predcited genes with no known function, leading some to dub the genes fun (function unknown) genes. a)As an approach to understanding the function of a certain fun gene, you wish to create a loss of function allele. How would you do this? b)You wish to know the physical location of the encoded protein product. How would you obtain such information?arrow_forwardA yeast strain with a mutant spo11- allele has been isolated. The mutant allele is nonfunctional; it makes no spo11 protein. What do you suppose is the phenotype of this mutant strain?arrow_forwardYou are studying a large eukaryotic gene that is 439,515 base pairs long. You find the polypeptide that this gene produces in liver cells is 46,771 amino acids long. Your colleague studies the function of this gene in brain cells, and finds the polypeptide produced in the brain is much larger – 61,438 amino acids long. How do you explain this difference? Possible Answers: A. The cell cycle of liver cells is much longer than that of brain cells. B. This is due to alternative splicing. in the brain C. There was a different complement of sequence-specific transcription factor binding sites in the CRM of the brain cells. D. There is no 5' cap added to the gene product from the liver cells.arrow_forward
