You are investigating the report of a UFO landing in an isolated portion of New Mexico, and encounter a strange object that is radiating sound waves uniformly in all directions. Assume that the sound comes from a point source and that you can ignore reflections. You are slowly walking toward the source. When you are 7.5 m from it, you measure its intensity to be 0.11W/m2.

An intensity of 1.0W/m2 is often used as the "threshold of pain". How much closer to the source can you move before the sound intensity reaches this threshold?

A small portion of a population migrates to an isolated island. Its genotypic frequencies are 0.8 AA, 0.1 Aa and 0.1 aa. These individuals start a new population on this island. What phenomenon is being described here? Calculate the allele frequencies for this new island population. Assume that this population is not undergoing evolution and undergoes random mating. What genotypic frequencies will you see in this population after one generation of random mating? What will the allele and genotype frequencies...

Genetics students were studying protein synthesis in the protozoan Tetrahymena. The students isolated a portion of the nucleic acid sequence, which codes for the C terminus of a Tetrahymena protein, which is: AUU AUG UAU AAG UAG GUC GCA UAA ACA CAA UUA UGA GAC UUA I M Y K Q V A Q T Q L stop However, the students were unable to translate purified Tetrahymena mRNA in an in vitro system as the translation products were mostly...

You just isolated a new strain of mutant mice, and preliminary mating suggest that the new mutant phenotype is not inherited in an autosomal fashion. Circumstantial evidence seems to indicate that the mutant phenotype may be following either an X-linked dominant or a mitochondrial-type inheritance pattern. a.) What two informative crosses would you set up to distinguish between these two possibilities? b.) How would the results distinguish between the two possibilities?

You studied a small, isolated human population and identified a new gene A. You found these numbers of individuals with these genotypes (capital letter represents dominance): 250 individuals of AA genotype, 500 individuals of Aa phenotypes and only 1 aa genotype, who is a 3 years old boy. Is gene A in Hardy-Weinberg equilibrium? Describe the possible reasons why gene A is (or isn’t) at HardWeinberg equilibrium. What can you conclude from the collected data?

You work for the Colorado Chapter of the Mutual UFO Network (MUFON) that is responsible for compiling all UFO sightings in the US. You are interested in whether there is a difference between rural and urban people in the mean number of UFOs they have ever seen. You randomly sample 200 urban and 150 rural Coloradoans and ask how many UFOs they’ve seen. Of the urbanites, the mean number of UFOs is 1.3 UFOs with a standard deviation of .4....

You have just isolated a new strain of Gram negative bacteria that can catabolize the sugar aspartame. Genome comparisons to all other strains don't provide any insight into the identity of this pathway. 1) Describe an experiment to identify the pathway coding for aspartame catabolism 2) Describe an experiment to move this pathway into E. coli 3) Given what we learned in class, describe how this pathway is likely positively regulated and where promoter sequence would be 4) Describe an...
