Textbook Question
Chapter 24, Problem 2S
One of the common misconceptions about sequencing projects (especially the high-profile Human Genome Project) is that creating a complete road map of the DNA will lead directly to cures for genetically based diseases. Given the percentage similarity m DNA between humans and chimps, is this simplistic view justified? Explain.

Students have asked these similar questions
What are some of the technical challenges of cloning a mammoth? Check all that are true
Ancient mammoth DNA has degraded so it is hard to know the complete genome sequence
Mammoth gestation time is likely too short to allowing cloning
A living surrogate mother would have to be used, which could pose problems since the closest relative to mammoths is endangered elephants
A living oocyte would have to be obtained from an extant species, which could pose problems since the closest relative to mammoths is endangered elephants
Mammoths lived so long ago that they used a different genetic code than modern animals
There are no enzymes in existence that could ligate together mammoth DNA sequence with elephant sequence
Mammoths probably had egg shells, which would be hard to penetrate with a needle
Describe the three basic goals of the Human Genome Project. What are at least three things we have learned from the project? Do you believe it was a worthwhile project? Why or why not?

- Increasingly, whole-genome sequencing of individuals is being done to help identify and treat medical conditions. Genome sequencing invariably identifies a number of variations, some common and some rare, that might be clinically relevant. For example, suppose a person had their genome sequenced to help determine their risk for cardiovascular disease and, just by chance, the sequence revealed that they carry one or more variants that predispose them to cancer or Alzheimer disease. Does the sequencing laboratory or physician have an obligation to report this finding, which was not the purpose of the sequencing and which the patient did not request? What about reporting variants for which no or limited information can be provided about their clinical significance? Does the answer to this question differ for sequencing done on children?arrow_forwardThe idea behind PCR-based diagnostics is that a very small number of microbial genomes in a patient sample can be multiplied by PCR and more easily detected by the clinical team managing the patient’s care. Also, genetic-based diagnostics are very useful for viral infections because we don’t have biochemical tests, etc. to distinguish one virus from another (remember, viruses are metabolically inactive). However, a lot of work goes into the development of these tests. For instance, PCR requires primers that are complementary to the viral genome that is being copied. If primers are complementary to the target genome, what must scientists know to design primers that bind to the viral genome to be copied? (I mean this to be a general question; don’t look up the details of designing primers)arrow_forwardBioinformatics is an interdisciplinary field that integrates knowledge of computer science with mathematics and statistics to solve biological questions.

For each pair of organisms determine the genetic distance between them. The genetic distance is simply the percentage difference between the two genes. Since each sequence is 50 base bases long, the genetic distance will be 2x the number of base differences.
