Watson and Crick used scientific reasoning, their knowledge of biochemistry, and the research of other scientists to make one of the most important scientific claims of their time: DNA is a double helix with strands running in opposite directions. Between these strands, A pairs with T, and C pairs with G.

Which of the following is true about the structure of DNA as proposed by Watson and Crick (B-form DNA)? A. DNA forms a left-handed double helix. B. The strands of DNA are parallel. C. The complementary base pairs are held together by hydrogen bonds. D. A complete turn of the double helix occurs after every base pair.
If one side of a DNA molecule has the base sequence A T C G G G C C A A C C, what would the sequence be on the complementary strand?
Using the figure below, which end of the double helix,"A" or "B", would be considered the 5 prime end? B (type "A" or "B" in the blank) Which of the following statements would best explain your reasoning for question 1? 1 (type 1, 2 or 3 in the blank) The end of the DNA strand with the phosphate exposed is the 5 prime end The end of the DNA strand that shows the five carbon sugar pointing down is the 5 prime end The end of the DNA strand with the fifth carbon on the sugar molecule is the 5 prime end
Your lab partner tells you proteins are used to make enzymes, you say, no enzymes are used to make proteins. Who is right? Explain your answer. – realize that enzymes are proteins and that the enzyme polymerase is used to transcribe DNA
While trying to determine the structure of DNA, Watson and Crick at one point proposed that like bases are bonded to like bases. For example, thymine would be bonded to thymine, cytosine would be bonded to cytosine, and so on. Explain why this proposed model would not fit based on what was discovered to be true about DNA.
Why do you think all organisms use nucleic acids for encoding genetic information? Why not use proteins or carbohydrates? What advantages might DNA have as the source of genetic information?
Which statement BEST describes the arrangement of components in a DNA molecule? The A, T, C, G four bases as well as the phosphates are located toward the inside of the strands. The A, T, C, G four bases are located toward the inside of the strands and the phosphates toward the outside. The A, T, C, G four bases are located toward the outside of the strands and phosphates toward the interior. The A, T, C, G four bases as well as the phosphates are located toward the outside of the strands.
Which of the following is NOT true of the structure of DNA? Select one: a. The backbone is made up of alternating sugars and phosphates. b. Nitrogenous bases A and C bond together, and bases T and G bond together. c. It contains all of the genetic information for an individual. d. The molecule has the shape of a coiled ladder.
Which of the following is one of "Chargoff's rules", one of the things he discovered? That DNA is a uniform molecule That there are two coils in a DNA molecule That nucleotides "base pair" That DNA contains an equal amount of Thymine and Adenine, and an equal amount of Cytosine and Guanine
Is the structure of Human DNA same as the Bacteria DNA?
Which of the following is false regarding a DNA molecule? a-It contains a double helix structure b-It stores genetic information c-It contains the nitrogen base Uracil d-It contains base pairs
Which of the following statements about DNA is true? The two strands are held together by hydrogen bonds. In deoxyribose, the 2' C has an OH attached to it. Positive supercoils promote strand separation. Z DNA forms a right-handed helix. One strand is positively charged while the other is negatively charged.
