Are the following examples a description of genetics at the molecular, cellular, organismal, or populational level?
A. People with cystic fibrosis have lung problems due to a buildup of mucus in their lungs
B. The mutant CF gene encodes a chloride transporter that doesn't
transport chloride ions very well.
C. A defect in the chloride transporter causes a salt imbalance in lung cells.
Model organisms are those widely used by researchers who wish to understand basic processes that are common to many species. Bacteria such as Escherichia coli are model organisms for modern geneticists. Give three reasons why bacteria would be useful in genetic experiments.
Most of the genetic information we will get from our genome will not be hard evidence that we will or we won’t get a disease but is rather only probabilistic evidence.
a. What does this mean?
b. Why might knowing a single gene not tell you if you will get a particular condition?

- A researcher examines genes for several proteins that are quite similar in both structure and function. He is interested in determining whether the genes form a multigene family and in working out which of the proteins arose first evolutionarily. What would be the BEST approach to take to address this question? Be careful to look for the best approach; some other approaches could also provide useful information while being less definitive. A. The researcher should sequence the genes and compare their sequences. The most similar genes are likely the most closely related, while those that have more base differences probably diverged earlier. B. The researcher should examine the functions of the proteins. Those with the most similar functions are the most closely related. C. The researcher should induce mutations in the genes to see how these affect the function. The most mutations needed to cause changes in the function of the protein, the older the gene. D.

- You were taking care of your heffalumps, and you notice that a few of the new babies have a strange phenotype you’ve never seen before. They are polka-dotted! You decide to sequence samples from the polka-dot babies to find the mutation that caused this novel phenotype. What kind of genetics is this? a. Reverse Genetics b. Epigenetics c. Forward Genetics d. Genomics e. None of the abovearrow_forwardSuppose 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.arrow_forwardWrite a paragraph describing the evolutionary forces driving changes in the human genome. You can include evolutionary forces such as random genetic drift, mutation, migration, and natural selection. These forces would have long-term and short-term effects on coding and non-coding DNA, the abundance of transposable elements, and the birth and death of genes. You can focus on a subset of the human population, or the entire species.arrow_forward

The inserted gene is usually from another species. The purpose of this manipulation is to give the target organism and its offspring a new trait that improves it in some way. The improvement might, for example, give the organism higher vitamin content. The process is called genetic engineering. 1. What are genetically modified organisms? 2. What is Genetic engineering?arrow_forwardGenetic engineering has been a debatable topic in science as many people are only aware of its risk than benefits. Which among the scenarios below are the benefits of using GMOs? I. Genetic engineering in food can be used to alter genes in crops leading to new diseases in pants. II. Genetic engineering in crops such as rice, corn and tomato can be used to obtain new strains with better nutritional qualities. III. Genetic engineering in food can be used to create totally the same substances such as proteins and other food nutrients. IV. Genetic engineering can be used to increase the immunity to diseases in plants leading to uncontrolled transfer of the resistance genes to the harmful pathogens. V.
