Which of these concerns regarding genetically engineered crops is a possibility?
  1. Genes engineered to make a plant resistant to pests, disease, and herbicides may transfer to undesired species, creating unusually robust weeds.
  2. Genetically engineered vegetables may contain genes that transfer into humans when ingested, producing mutations.
  3. Genetic engineering is a new field, and as such there may be adverse long term effects that arise from genetically engineered crops.
  4. Genetically engineered crops are too robust and may overgrow all other plants in their areas, eliminating biodiversity near croplands.

How does human gene therapy treat or cure diseases?
  1. Human gene therapy replaces certain genes within a patient with other variations of their genes, producing more variation in the individual, thusly allowing them to recover from diseases more quickly.
  2. Human gene therapy introduces new engineered genes in an effort to prevent the spread of cancers.
  3. Human gene therapy replaces human genes that were mutated or damaged with engineered genes, in some cases curing patients entirely.
  4. Human gene therapy replaces human genes that were mutated or damaged with engineered genes, though the process must be repeated periodically to replace genes that are naturally produced by the patient
Grade 9 :: DNA, RNA, and Genetics by McBobbo
Which of the following statements regarding linked genes is correct?
  1. Two genes in close proximity on the same chromosome tend to be inherited and are considered linked.
  2. The closer together genes are found on the same chromosome, the more likely they will be to recombine with other genes.
  3. Linked genes are commonly used as an example to support Mendel's law of independent assortment.
  4. All of the above
Grade 9 :: DNA, RNA, and Genetics by mpjose
What do scientists use to predict traits in offspring?
  1. genotype
  2. phenotype
  3. probability
  4. pleiotropy
Grade 9 :: DNA, RNA, and Genetics by mpjose
Grade 9 :: DNA, RNA, and Genetics by McBobbo
What was the focus of the Human Genome Project?
  1. The Human Genome Project was focused on determining the likelihood of specific human genotypes for specific ecosystems.
  2. The Human Genome Project was focused on finding methods to use human genetic engineering to reduce the prevalence of genetic diseases.
  3. The Human Genome Project focused on mapping the location and sequence of human genes as well as to determine the nucleotide sequence of all human DNA.
  4. All of the above
Grade 9 :: DNA, RNA, and Genetics by McBobbo
Suppose a singular nucleotide is added to a sequence of DNA. How will this affect the polypeptide?
  1. This change will effect the polypeptide, enhancing its effectiveness.
  2. This small change in the DNA will not produce noticeable results. A greater number of changes would be necessary to produce a mutation.
  3. This small change in the DNA will cause a mutation and may cause the polypeptide to become nonfunctional.
  4. The addition of a nucleotide always produces a stop codon, therefore the protein will be prematurely terminated.
Grade 9 :: DNA, RNA, and Genetics by McBobbo
Which of the following statements regarding sex chromosome abnormalities is incorrect?
  1. Individuals with three X chromosomes are indistinguishable from individuals with only two X chromosomes except by karyoptype.
  2. Individuals with two X chromosomes and one Y chromosome are abnormally tall females of average intelligence.
  3. Individuals with only a single X chromosome are females who exhibit Turner Syndrome and are sterile.
  4. Individuals with two X chromosomes and one Y chromosomes are sterile males that can experience breast enlargement and other female appearances if untreated.
Grade 9 :: DNA, RNA, and Genetics by mpjose
What Law describes how chromosome pairs separate during meiosis?
  1. Law of Independent Assortment
  2. Law of Segregation
  3. Law of Dominance
Grade 10 :: DNA, RNA, and Genetics by tdaranykone
Changes in the DNA sequence that affect genetic information are known as
  1. replications.
  2. mutations.
  3. transformations.
  4. prokaryotes.
