- Q1What enzyme is responsible for adding nucleotides during transcription?helicaseprimaseRNA polymeraseDNA polymerase30s
- Q2What is not a difference between RNA and DNA?DNA has deoxyribose and RNA has riboseDNA is double stranded and RNA is single strandedDNA stores genetic information and RNA transmits genetic informationDNA has uracil and RNA has thymine30s
- Q3During what phase of mitosis is there a checkpoint and why?During prophase to make sure that all chromosomes were duplicated during the S phase of interphaseDuring anaphase to make sure that chromatids separated correctly and evenlyDuring telophase to make sure there is a correct number of chromosome before the nucleus returnsDuring metaphase to make sure chromatids are paired and lined up correctly before division30s
- Q4What is the purpose of cyclin-kinase during the cell cycle?to promote cell divisionto repress cell division30s
- Q5Which of the following is not a negative regulatory molecule?Rbr45p53p2130s
- Q6What phase of the cell cycle is shown above?metaphasetelophaseprophaseanaphase30s
- Q7Which of the following does not occur during interphase?spindle fibers attach to chromosomesorganelles are duplicatedthe cell growsDNA is replicated30s
- Q8Which of the following amino acids does the codon AUG give you? (Click chart to enlarge)Leu.Arg.Met.Ser.30s
- Q9What would be the anti codon of CGAGCUTACCGAGCT30s
- Q10Which of the following is the first step to protein synthesis?snRNA edits mRNA and mRNA leaves the nucleus to the ribosomehelicase unwinds DNA and RNA polymerase adds complementary nucleotidestRNA brings amino acids to the ribosome to bond together to make proteinRNA polymerase adds nucleotides and snRNA edits mRNA30s
- Q11During which checkpoint does the cell make sure the conditions are favorable for division?G1/SG1Mnone of these30s
- Q12What type of RNA can be found in the cytoplasm?rRNA, tRNA, mRNArRNA, snRNA, tRNArRNA, snRNA, mRNAmRNA, snRNA, tRNA30s
- Q13What process does this diagram show?protein synthesistranscriptionreplicationtranslation30s
- Q14Which of the following does not correctly describe cancer cells?cells that have mutations the gene for regulatory moleculescells that grow too largecells that rapidly growcells that do not go through cell cycle checkpoints30s
- Q15What type of mutation is show in the image above?insertionsubstitutiondeletionduplication30s
