Concept explainers
Enzymes that break down DNA catalyze the hydrolysis of the covalent bonds that join
(A) The two strands of the double helix would separate.
(B) The phosphodiester linkages of the polynucleotide backbone would be broken.
(C) The pyrimidines would be separated from the deoxyribose sugars.
(D) All bases would be separated from the deoxyribose sugars.

- In a DNA double helix, why doesn't an A or T form two hydrogen bonds (out of the three possible ) with G or C? Explain how DNA replication is bidirectional and discontinuous in nature?arrow_forwardThe two strands of a DNA double helix can be separated by heating. If you raise the temperature of a solution containing the three DNA molecules below, in what order do you think these DNAs will "melt"?

- How do we know that the structure of DNA is in the form of a right-handed double-helical molecule?arrow_forwardSuppose a piece of DNA is cut into four fragments of varying sizes. Where would you expect to find the larger fragments on the gel (top, middle, or bottom)? Why? Suppose you had 1000 pieces of each of the four fragments, how many bands would appear on the gel?arrow_forwardWhat role does bonding play in DNA? Where are hydrogen bonds located? Where are covalent bonds located? Why is that significant to the overall structure and function of DNAarrow_forward
- The base composition of one of the DNA chains of a DNA double helix contains 18 mol-%A, 35 mol-%T, 26 mol-%C, and 21 mol-%G (a) What is the base composition of the complementary DNA chain? (b) Is the total amount of purine bases equal to the total amount of pyrimidine bases for the DNA double helix?arrow_forwardCan you: describe the 2 D and 3 D structure of DNA including the bonding that takes place?arrow_forwardWhy do higher salt concentrations stabilize the DNA double helix? Or What aspect of the structure of double-stranded DNA destabilizes the helix in the absence of salt?arrow_forward
- What type of DNA helix spirals to the left and the backbone takes on a zigzag shape?arrow_forwardDNA solution is viscous because of the nature of chemical substance that can intercalate into the DNA helix. An example of such substance is acridine orange. experiments revealed that acridine orange causes an increase in the viscosity of DNA solution.how would you account for this effect?arrow_forwardWhat describes or designates the 3' end of a DNA strand? a. an available hydroxyl group on the 5th carbon of a deoxyribose of a terminal nucleotide b. an available phosphate group on the 3rd carbon of a deoxyribose of a terminal nucleotide c. an available hydroxyl group on the 3rd carbon of a deoxyribose of a terminal nucleotide d. an available hydroxyl group on the 2nd carbon of a deoxyribose of a terminal nucleotidearrow_forward
