front 4 A mutagen is | back 4 an agent that causes a mutation in DNA. |
front 5 Which type of mutation always produces a stop codon? | back 5 Nonsense |
front 6 A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred? | back 6 Silent |
front 7 The DNA sequence reads ACGTTCATT before a mutation occurs. After the mutation, the DNA sequence reads ATCGTTCATT. Which type of mutation occurred? | back 7 Insertion |
front 8 Ji wants to write an example of a frameshift mutation using the following sentence: THE CAT SAW THE RAT. Which sentence best shows a frameshift mutation? | back 8 THC ATS AWT HER AT. |
front 9 Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage Which type of mutation causes sickle cell anemia? | back 9 Missense |
front 10 Based on scientific research, which statement best describes mutations? | back 10 Mutations are rare occurrences. |
front 11 Many different types of mutations can occur within the body. Tay-Sachs disease is a deadly disorder that is caused by a missing codon in the gene coding for production of the hex A enzyme in the body. Which type of mutation is responsible for causing Tay-Sachs disease? | back 11 Deletion |
front 12 Which is considered a chemical mutagen? | back 12 Tobacco |
front 13 A scientist thinks that a certain chemical is a mutagen. She exposes
plant cells to a large amount of this chemical in the
laboratory. | back 13 The cells change after being exposed to the chemical, and this change is passed to the next generation of cells |
front 14 Which statement is scientifically based? | back 14 Mutations rarely occur. |
front 15 Which best describes genetic mutations? | back 15 Some inherited genetic mutations can be good for the offspring. |
front 16 Which best describes somatic mutations? | back 16 They can cause different kinds of cancer. |
