Slide 9 (Answer) / 50 Slide 10 / 50 6 Which of the following is not a function of the 7 Which of the following accurately reflects the DNA nucleus? material found in eukaryotic cells? A to produce rRNA A A eukaryotic cell contains only the portions of the DNA Answer material needed to perform its function. Answer to safely store DNA B D B A eukaryotic cell contains half the number of to ensure transcription into RNA C chromosomes of the eukaryotic organism. D to ensure translation into proteins A eukaryotic cell contains all of the genes required for the entire organism, but only certain genes are expressed in C each cell. [This object is a pull tab] A eukaryotic cell contains all of the genes required for the entire organism and therefore can change from one type D of cell to another quickly. Slide 10 (Answer) / 50 Slide 11 / 50 The image below represents the structure of DNA 7 Which of the following accurately reflects the DNA as seen in various magnifications. Use this material found in eukaryotic cells? illustration to respond to questions 8 and 9 below. A A eukaryotic cell contains only the portions of the DNA material needed to perform its function. Answer C B A eukaryotic cell contains half the number of chromosomes of the eukaryotic organism. A eukaryotic cell contains all of the genes required for the entire organism, but only certain genes are expressed in C each cell.
