- Q2Making recombinant DNA is described as genes of interest contained in the DNA fragments are united with vector DNA, which are then bonded together with DNA ligase.FalseTrue30s
- Q3Which statement best describes Eugenicsthe study of human genes and their transmission from generation to generationthe combining of genes from two different species to form new organismsthe study of the genomes of eubacteriaThe use of selective breeding and sterilizations to improve the human genome30s
- Q4Genetic testing can be sued to evaluate if a person carries the genetic mutation, BRCA 1 or 2 genes, that cause breast cancer. What is one disadvantage to this type of test?Personal health insurance premiums could risePersonal decisions about getting genetic testing may increasePersonal diagnoses of cancer could be detected earlier.Personal choices regarding lifestyle could reduce cancer risk.30s
- Q5Scientists want to isolate a particular gene to be transformed into another organism. What is one of the steps they need to take to make this happen.Cut the DNA into fragmentsChemically terminate the transcription processRun a karyotype of the genomeMake the DNA larger for easier access30s
- Q6The term genetic engineering is best described astransferring genes from the genetic material of one organism to the genetic material of another organismcausing organisms to evolve by changing their nucleotide sequences in the zygotecreating new organisms by combining the genes of several different organismscreating new DNA strands from old DNA strands30s
- Q7DNA formed by combining the DNA from two different species of an organism is calledRNAteenage mutant ninja turtlesretroactive DNArecombinant DNA30s
- Q8Which of the following best explains why a student researching genetics should use the most recent textbooks available?research in Mendelian genetics began very recentlyolder textbooks are more difficult to understandnew discoveries frequently add to older knowledge in geneticsno technologies from more than ten years ago are still in use30s
- Q9The process shown in the figure is called?binary fissionpropagationconjugationrecombinant DNA30s
- Q10The process in the figure frequently used in agriculture is known as?transferencecloningrecombinant DNAtransduction30s
- Q11The process of gene therapy -can be used to cure a genetic disease and the cure is then transmitted to a patient's offspringis not currently capable of being used to treat humansto make people grow tallercan be used to treat some human diseases such as sickle cell disease30s
- Q12What is NOT an example of DNA technology currently used in agriculture?The cloning of human nerve cells from corn plantsThe development of pesticide resistant crop plantsThe use of growth hormones produced from recombinant bacteria to increase milk productionThe development of frost resistant crop plants30s
- Q13The equipment listed above is used in a biotechnology technique called?Gel electrophoresisRecombinant DNACloningGenetic engineering30s
- Q14What is one negative aspect of genetic engineering?Genetic engineering can enhance the nutritional value of cropsGenetic engineering can make crops more tolerant of drought conditions and different soils.Genetic engineering can indirectly modify weeds making them resistant to weed killersGenetic engineering can control the rate at which fruit ripens.30s
- Q15Medicines are being produced using recombinant DNA technology. For veterinarians, the use of this DNA technology will result indecreasing the number of antibodies produced by petsidentify new diseases spread by petsmaking more treatments available to petsaltering the chromosome of healthy pets30s
