- The zebra danios are a new type of pet fish, marketed as Glo-Fish. The fish were produced by transferring genes from jellyfish (green and yellow fish) and corals (red fish) into regular zebra danio fish (striped blue and white normally) embryos. Which of the following statements is true about these fish? O These fish have recombinant DNA They have been selectively bred. They are now photosynthetic This happens naturally in the wild.Which of the following patterns was observed, in the experiments of Hershey and Chase, using the T2 bacteriophage of E. coli? radioactive proteins were passed on to viral progeny, but not radioactive polynucleotides radioactive polynucleotides were passed on to viral progeny, but not radioactive proteins both radioactive proteins and radioactive polynucleotides were passed on to viral progeny both radioactive polynucleotides and radioactive proteins were passed on to viral progeny neither radioactive proteins nor radioactive polynucleotides were passed on to viral progenymtDNA depletion syndrome 13 is a rare genetic disorder, in which individuals have fewer mitochondria in the muscles than normal because the organelles are degraded by lysosomes. Would this disorder impact the muscles' ability to perform the Cori Cycle? O Yes, it would interfere with lactic acid fermentation. O Yes, it would interfere with aerobic gluconeogenesis. O Yes, it would interfere with anaerobic glycolysis. O No, it would not impact the Cori Cycle.

- Why do scientists believe that the sickle-cell trait has not evolved out of the human population yet considering how deadly it is to be homozygous for the sickle cell gene?Y-STR and mtDNA tests have less impressive statistical weights than autosomal tests because..... They undergo a mutation rate that is at least ten times greater than that of nuclear genes There are thousands of copies of each in every cell and their information is redundant They both contain a relatively small number of genes and all are under strong selective constraint They are both involved in cytoplasmic inheritance and approximately 10% of individuals have been found to be chimeras They are paternally and maternally inherited, respectfully, and there is therefor no opportunity for recombination to occurIs each of these statements true of chloroplast or mitochondrial genomes, both, or neither? a.contain tRNA genes
- Assume that the molecular clock for the alcohol dehydrogenase (Adh) gene in Drosophila ticks at a rate of 5 X 10-⁹ substitutions per bp per year. On a volcanic island you find two species of Drosophila, descended from one species that colonized the island sometime after it first rose out of the ocean. You sequence the Adh genes of the two species and find they show 5 synonymous substitutions in 1,000 bp. 2A. What is the rate of divergence between these 2 species of Drosophila? (Hint: Recall that substitutions are happening in both species.) 2B. How long ago did the two species diverge? 2C. How old is the island? Hint: you cannot give an exact age.The most common allele of the β chain of hemoglobin in humans, ???,HbA, has glutamic acid at the sixth position. Two different amino acid substitutions at the sixth position produce two variants, ???HbS and ???,HbC, of the sickle‑cell allele. The ???HbS allele occurs when valine is substituted for glutamic acid, and the ???HbC allele occurs when lysine is substituted for glutamic acid. To answer the question, refer to the amino acid table. Match the class of amino acid and the chemical property to each possible amino acid. Not all answers will be placed.The tiny frog Paedophryne amauensis was discovered by researchers purposefully searching for the source of an unusual sound, but sometimes similarity between two species can lead scientists to accidental discoveries. A previously unknown species of wild cat was inadvertently discovered by researchers who were sequencing the DNA of a house cat–sized South American wild cat called the tigrina. The DNA analysis revealed that many alleles found in the supposed tigrinas living in northeastern Brazil are not shared with other tigrinas. This finding suggested that the northeastern cats do not interbreed with other tigrinas and are therefore a different species. What prevents the two species from interbreeding?
