- Identical twin brothers begin life with identical genomes andepigenomes. How will this circumstance change with age?Suggest how these changes could be used as a forensic tool.Imagine that you become a parent in an age when a full genetic workup is available for every baby. What advantages and disadvantages might there be to having this information?Explain what happens to the sequence of DNA during trinucleotiderepeat expansion (TNRE). If someone was mildly affected with a TNRE disorder, what issues would be important when considering possible effects in future offspring?
- Wooly Mammoths have been extinct for about 10,000 years; however, their remains have been well persevered in Siberia. Due to global warming, these remains are now available to be recovered. Scientists want to extract the DNA and through cloning insert the DNA into an elephant to clone the mammoth. What are some of the pros and cons of cloning an extinct animal?an orginal dna sequence retrieved from the gametes of a female golden retriever and a mutated dna sequence fro her puppy are found below. how will this mutation effect descentants of this puppyComment on the utility of variability in number of tamndem repeats during DNA fingerprintingds?
- Would the horse make a good model genetic organism? Why or why not?(a) How does the duplication of individual genes occur? (b) individual that inherit a genetic condition known as xeroderma pigmentosum exhibit an extreme sensitivity to sunlight exposure and often develop skin cancer by the age of 10. What repair pathway is most likely disrupted as a result of such mutation? Explain why?Ronan Farrow, son of the actress Mia Farrow, has grown up thinking that Woody Allen is his father. But Vanity Fair broke the story that Frank Sinatra might be Ronan's actual father. Vanity Fair would like to confirm the story but they are almost bankrupt. So they hire you. You're also almost bankrupt and can't afford to pay for full genome sequencing. You should be able to solve the case by sequencing a short stretch of DNA from one chromosome from Ronan and comparing it to a sequence from the same chromosome in Woody Allen. Which chromosome would you choose for your sequencing project v Choose... X-Chromosome It turns out that Woody Allen will not cooperate with this project. Ba Any autosomal chromosome nce Y-Chromosome information from which living individual, if any, can you use to solve the Relatives of Woody Allen Relatives of Frank Sinatra Woody Allen Mia Farrow Mia Farrow Frank Sinatra 4 4 6 II 1 ? II ? 2 Ronan might be Woody's son Ronan might be Frank's son 3. 2.
- Suppose that you could undergo genetic testing at age 18 for susceptibility to a genetic disease that would not appear until middle age and has no available treatment. a. What would be some of the possible reasons for having such a genetic test and some of the possible reasons for not having the test? b. Would you personally want to be tested? Explain your reasoning.1) Do you agree or disagree with this statement? Transposons can cause genomic rearrangements or genomic expansion compared to microsats, which are only associated with genomic expansion. Explain your response. 2) Do you agree or disagree with this statement? Since bone is a non-living structure, it would not be useful for genomic profiling. Explain.Evidence [see P. G. Shiels, A. J. Kind, K. H. Campbell, et al. (1999),“Analysis of telomere lengths in cloned sheep,” Nature 399, 316–317] suggests that Dolly may have been genetically older than heractual age. As mammals age, the chromosomes in somatic cells tendto shorten from the telomeres. Therefore, older individuals haveshorter chromosomes in their somatic cells than do younger ones.When researchers analyzed the chromosomes in the somatic cells of Dolly when she was about 3 years old, the lengths of her chromosomeswere consistent with those of a sheep that was significantlyolder, say, 9–10 years old. (Note: As described in the chapter, thesheep that donated the somatic cell that produced Dolly was 6 yearsold, and her mammary cells had been grown in culture for severalcell doublings before one of the cells was fused with an oocyte.)A. Suggest an explanation why Dolly’s chromosomes seemedolder than they should have been.B. Let’s suppose that a female sheep (like Dolly), which…
