Some genes evolve more rapidly than others. But how can this be demonstrated?
Step by step
Solved in 2 steps
- We each carry 20,000 genes in our genome. Genes can be patented, and over 6,000 human genes have been patented. Do you think that companies or individuals should be able to patent human genes? Why or why not?After watching the video “Genes as Medicine" discuss how gene therapy has been used to treat an inherited form of blindness, and now sickle cell anemia. How were the genes delivered? What model organism was gene therapy tested in? How successful has the treatment been in humans?Gene therapy is currently a fairly expensive treatment. For rare conditions, the fewer the people treated, the more expensive the treatment will be. But whatis the right price for a cure?
- How might a point mutation in DNA affect the phenotype. How the genome is expressed in the organism? (Please explain this at the molecular level).Some bacteria might be able to respond to environmental stress by increasing the rate at which mutations occur during cell division. How might this be accomplished? Do you think there would be an evolutionary advantage of this ability? Explain.A biology professor at a prestigious university stated to his introductory class that "Today, a basic understanding of DNA and genetics is as important as a basic understanding of computers and the internet."Based upon what you have learned about DNA and gene expression in this module, how could you make a case to support this statement?
- Gene duplication creates genes that are under what kind of selective pressure? How does this lead to the formation of new, beneficial traits?To cause cancer, proto-genes require blank allele(s) to be mutated and therefore are considered blank.Why can’t all genetic diseases be treated with gene therapy ? Explain how the ideal procedure for gene therapy would work ?
