You will need to brainstorm for several minutes on how you could extend the life of dogs. You should refer to the example of the fruit flies from lecture.As part of this project, the breeders will need to put together an informational brochure to hand out to veterinarians and prospective owners of the dogs, which discusses: first, how dogs' age will be extended, then, some of the potential consequences of having a pet that lives for such a long time. The brochure will need to inform prospective owners that these dogs may live 40 or more years. It should point out that someone who is 30+ years old may have to plan on care for the pet if it were to outlive him or her. Also, there will be more lifetime costs associated with these dogs simply because they live so long. These dogs may be prone to diseases that are not seen in dogs with shorter life spans. Finally, there may be…arrow_forwardDraw a schematic diagram of how we can treatment the Cystic fibrosis by using gene therapy? Please draw at your own hands.arrow_forward
- A researcher studies a mutation that occurs in humans and writes four facts about the mutation in a chart. 1. The mutation is caused as a result of chance. 2. The mutation leads to a genetic disease. 3. The mutation occurs in sperm cells and is passed to the next generation. 4. The mutation is not discovered or fixed by the cell's enzymes. Based on the information, the researcher concludes that the mutation is harmful. Which statement best supports the researcher's conclusion?

When amplified, the fragments of DNA containing the mutated gene alleles were 250 base pairs long and the normal (wild type) alleles were 350 base pairs long. To identify the genotypes of the individual nematodes, the researcher used gel electrophoresis to visualize the PCR results. 1.000 bp 500 bp 300 bp 200 bp 100 bp Remember that these nematodes are diploid organisms and as such, inherited two copies of Gene Y. Which of the following statements is a correct analysis of these results a) Nematode As homozygous for this gene and has two copies of the mutated allele. O b) Nematode C is heterozygous for this gene and has one copy of the mutated allele and one copy of the normal (wild type) allele.
