What type of mutations does EMS cause? a. Mismatched bases d. Insertions and deletions c. Chromosome breaks d. Pyrimidine dimers e. Deamination of cytosine In bacteria, which of the following is true? a. Repressors bind to the DNA in between the first and second gene of the operon b. Repressors bind to the DNA just upstream of the promoter c. Activators bind to the DNA in between the first and second gene of the operon d. Activators bind to the DNA in between the promoter and the first gene of the operon e. Activators bind to the DNA just upstream of the promoter f. None of the above Which of the following is true about Mismatch DNA repair systems? a. the mismatch repair system removes nucleotides, then replaces them with the correct nucleotides and seals the nick in the backbone. b. The mismatch repair system replaces the mismatched base on the methylated strand c. the mismatch repair system works after DNA replication to fix errors not caught by DNA polymerase d. all of the above e. none of the above

Which type of enzyme synthesizes primers during the process of DNA replication? A) DNA polymerase B) RNA polymerase C) topoisomerase D) DNA ligase Which of the following types of enzymes would be involved in unwinding and rewinding (supercoiling) DNA during the process of DNA replication? A) DNA polymerases B) RNA polymerases C) topoisomerases D) DNA ligases Nucleotide incorporation errors which occur during DNA replication, and result in mismatched base pairs, can be corrected by the "proofreading function" of DNA polymerase. A) true B) false Exposure of bacteria and other types of cells to ultraviolet light (UV radiation) causes which type of DNA damage? A) base-pair mismatches B) pyrimidine dimers C) breaks in the phosphodiester backbone D) opening of the ring structure of bases

A gene encoding one of the proteins involved in DNA replication has been inactivated by a mutation in a cell. In the absence of this protein, the cell attempts to replicate its DNA. What would happen during the DNA replication process if each of the following proteins were missing? A. DNA polymerase B. DNA ligase C. Sliding clamp for DNA polymerase D. Nuclease that removes RNA primers E. DNA helicase F. Primase
Which of the following is NOT a way that transposable elements can cause mutations? a) Insertion into coding sequence b) Imperfect mobilization c) Recombination between transposons in nonhomologous chromosome regions d) Transcription of transposase The Ames test determines the potential for mutation in an unknown mutagen by measuring: a) How easily the mutagen "fixes" existing mutations b) The quantity of DNA changes produced c) Number of breaks per chromosome d) How well the mutagen intercalates into DNA
