- Q1If a farmer is concerned about profits, which of the following questions should be asked to decide whether or not to grow transgenic plants?d. Will the transgenic plant offer any information in studying human genesWill the transgenic plant require more pesticides?c. Will the transgenic plant help the farmer to produce more clones?a. Will the transgenic plant increase the amount of vitamins in crops?60s
- Q2A farmer is presented with two options. One option is to use a genetically modified corn plant, and the other option is to use a non-genetically modified corn plant. Which of the following questions could the farmer ask to determine the impact of growing GMO corn on the environment?“Will I be able to sell my corn for a higher price to earn a higher profit because it is a GMO corn?”"If I use GMO corn, am I able to plant them earlier in the year and grow them later into the year because they are more resistant to colder temperatures?”“Will I be able to increase the amount of corn I grow due to each plant producing more?”“Will I be able to use less insecticides because the corn will be more insect resistant?”60s
- Q3Scientists want to create citrus trees that are tolerant of cold weather. Currently, if the fruit from a citrus tree has not been picked and a freeze occurs, the fruit is damaged and cannot be sold. The scientists are studying how to alter the tree’s cells so that they are not damaged by the freezing temperatures. Which of these is a logical reason for continuing this research?The research could make it easier to preserve the picked fruit during storage and shipping.The research could help scientists alter human cells so that human skin is not damaged by frostbite.Plants that can tolerate the cold would be less likely to become infected by fungi.Plants that can tolerate the cold could allow citrus trees to grow in colder climates.60s
- Q4Which of the following statements is FALSE about genetic engineering?Recombinant DNA is created when pieces of DNA from two different species are joined.Genes from complex organisms such as animals can be inserted into bacteria or yeast.Genetic Engineering is used to produce large amount of proteins to treat certain diseases.Recombinant DNA is not passed down to offspring during reproduction.60s
- Q5Certain genetically modified tomatoes were designed to suppress the enzyme polygalactonase, which delays ripening. How does this gene modification affect the consumer and the diet of individuals?Delaying the ripening process means that the tomatoes are more likely to freeze on the vine before becoming ripe. This freezing process locks in the minerals and beneficial nutrients so that the tomato can be transported without losing its nutritional benefit.Delaying the ripening process means that the tomatoes have a longer shelf life. The tomatoes survive delivery to consumers and provide nutritional value to more people.Delaying the ripening process means that the tomatoes are more likely to have a shorter shelf life and have to be eaten quicker.Delaying the ripening process means that the tomatoes can stay on the vine longer to receive nutrients. Once picked, these tomatoes will ripen rapidly to provide a full taste to the consumer.60s
- Q6Which question may be asked and researched by someone who is arguing AGAINST the use of genetically modified crops?Have genetically modified crops allowed farmers to save money on insecticides and pesticides?Will genetically modified crops reduce the amount of land and energy used by farms because they have high yields?Will the prices of crops increase because the seeds for genetically modified crops are more expensive and this may drive small farmers out of business?Have genetically modified crops shown improvements in nutrition for consumer compared to non-genetically modified crops?60s
- Q7A student created a chart that outlines the advantages and disadvantages of GMOs to prepare for his science class debate. (image). The student made some mistakes while he was creating the chart. Which of the following would correct the mistake made by the student?Antibiotic resistance is a disadvantage, while cleaning up oil spills is an advantage.Both antibiotic resistance and longer shelf life are advantages.Developing herbicide resistant weeds is an advantage, and increasing crop productivity is a disadvantage.Antibiotic resistance is neither harmful nor helpful in society.300s
- Q8Which question could BEST be answered using the DNA Fingerprint above?Is individual C resistant to antibiotics?Could individual C be cloned?Are individuals B and D identical twins?Is individual A genetically modified?300s
- Q9The DNA profiles shown in the DNA fingerprint above represent four different individuals. Which of the following statements is consistent with the results?C is the child of A and B.A is the child of B and C.B is the child of A and C.D is the child of B and C.300s
- Q10Jack and Jill are thinking of having their first child and decide to have a genetic screening done before they attempt to have a baby. Both Jack and Jill have relatives who have the blood disorder Sickle Cell Anemia, but neither of them have the disease. Sickle Cell Anemia is a recessive disorder that causes malformation of red blood cells, meaning the child would have to inherit the gene from both parents to have Sickle Cell Anemia. When going over the results of Jack and Jill’s DNA fingerprint, the doctor explained that the presence of a band at 5kb means they carry the trait for Sickle Cell Anemia. Examine to the results in the image. Which of the following is a correct assumption about whether Jack and Jill’s child would be affected by Sickle Cell Anemia?No, the baby will not have Sickle Cell Anemia. Jill has the gene for the trait on her DNA fingerprint.Yes, the baby will have Sickle Cell Anemia. Both Jack and Jill have the gene for the trait on their DNA fingerprints.Yes, the baby will have Sickle Cell Anemia. Jill has the gene for the trait on her DNA fingerprint.No, the baby will not have Sickle Cell Anemia. Neither Jack nor Jill have the gene for the trait on their DNA fingerprint.300s
- Q11What does the following phrase refer to in the section? “During meiosis, only one copy of each allele went into each pollen or egg cell.”The principle of segregationThe process of genetic engineeringThe genetic limitations of blueberriesThe enhancement of the nutrient content of food300s
- Q12In this section “to modify the genetic material of living cells” involves?Adding one organism’s cells into another organismTaking care of living cells as they modify themselvesMoving or transfering genetic material between sourcesHelping organisms become resistant to bacteria300s
- Q13According to the section, traditional cross breeding:Has not been used to develop plants with desired qualitiesManufactures DNA to create new organismsTransfers many unwanted traits along with the trait of interestInvolves the removal and transfer of DNA from one organism into another300s
- Q14In order for the tomato to acquire the flounder fish’s cold resistant trait, a scientist needs to add the following to the tomato’s DNA:The genome of a flounder fishPasting enzymesA synthetic antifreeze geneUnbundled flounder chromosomes300s
