In the paper we read at the beginning of the term the coat color differences in the beach mice were driven by change in the melanocortin-1 (MCR-1) gene between the color morphs. Based on this information what can you conclude about the mutation causing the color change?
a.
It is a nonsynonymous substitution.
b.
The mutation is considered silent.
c.
The mutation is a transition.
d.
It is a synonymous substitution.
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?

- What happens to an organism (plant, animal, or microorganism) during genetic modification? A. Fewer desirable genes are transferred to a new species. B. Genes are removed from one organism and transferred to another. C. Plants or animals are given traits that they typically have. D. All of the abovearrow_forwardGene expression is a term that relates to Select one: A. DNA replication. B. the flow of genetic information from DNA to proteins. C. how genes are passed from parent to offspring. D. the unique set of genes in an individual.arrow_forwardYou are working in a lab that studies stickleback fish. These fish normally have three spines that occur on the back of the stickleback. One day you notice that a young stickleback has no spines on its back but instead has three spines growing out of the top of its head! (answer both questions) question 1: A mutation in what type of gene is probably the cause of this unusual situation? Why? question #2: would you expect the proteins that make the spines to be different in the mutant fish compared to a wildtype fish. Why or why not?arrow_forward

X-inactivation. b. metagenomic analysis of microbial communities. c. using proteins to inhibit transcription. d. using PCR to amplify copies of genes.arrow_forwardYou have been put in charge of developing a breed of domesticated dog that lives to be 40 years old on average. 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_forwardCloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other. Some pregnancies in humans have a similar result. Explain how identical twins are formed. Compare and contrast the natural formation of identical twins to the artificial embryo twinning process. Explain how the formation of identical twins or the process of artificial embryo twinning differs from the formation of fraternal twins.arrow_forward

- Which of the following best describes the mechanism of action of the antibiotic streptomycin? A. it disrupts protein synthesis in resistant bacteria. B. Streptomycin inhibits cell wall synthesis in all bacterial species. C. Streptomycin creates mutations in bacteria which cause them to become resistant. D. It disrupts protein synthesis in nonresistant bacteria.arrow_forwardWhich of the following is NOT a method by which bacteria can be resistant to antibiotics? Select one: a. Utilise an alternate pathway of gene expression that is not targeted by the antibiotic. b. Alter the binding site of the antibiotic, to either prevent it binding, or remove it from the site. c. Production of enzymes that bind to and break down the specific antibiotic. d. Production of a cell membrane pump that translocates antibiotics outside the cell. A potential side effect of antibiotic use is a secondary bacterial or fungal infection, usually associated with regions like the skin, upper-respiratory tract or genitalia. What is the most likely reason for the formation of these secondary infections? Select one: a. Antibiotics do not work on viruses, so they are able to establish infections in these locations. b. Organisms that are antibiotic resistant are usually more virulent, meaning they can survive and cause infection. c. The antibiotic kills off normal flora, providing an…arrow_forwardThe information that enables the organism to survive and is transferred from parent to offspring is found in a.
