- Answer : e Source : Campbell/Reece - Biology , Seventh Edition, EOC Process of Science Question Discussion Notes for the Instructor There are several questions which can be asked to guide the discussion of this question, including: Which isotope will the new nucleotides contain? As DNA is being replicated the new backbone (strand) will contain which isotope? How many templates are formed from one molecule of DNA? Using these questions as an outline. discussion of the choices might look like this: Choice A, since the original 14 N labeled backbones will act as templates with new 15 N nucleotides there should an intermediate band. Choice B, the intermediate band should have a mass exactly half way between the 14 N and 15 N marks Choice C, since there are no new 14 N labeled nucleotides there can be no bands that are just 14 N Choice D, since there are no new 14 N labeled nucleotides there can be no bands that are just 14 N Choice E, correct

- Answer : a Source : Campbell/Reece - Biology , Seventh Edition, EOC Process of Science Question Discussion Notes for the Instructor There are several questions which can be asked to guide the discussion of this question, including: What are the differences between the way the genetic information in prokaryotes and eukaryotes is packaged? How do transcription and translation differ in prokaryotes and eukaryotes? Using these questions as an outline, discussion of the choices might look like this: Choice A, correct Choice B, eukaryotes contain introns that are normally removed after transcription. In bacteria these introns would not be removed and then subsequently would be translated Choice C, the protein would not be expected to be longer if the mRNA is shorter Choice D, while it is possible for the protein to be shorter, owing to a termination sequence being found in what was an intron, this is unlikely.
