- 2) When DNA is placed in distilled water, which is pH 7.0, it denatures (i.e., the two strands separate). The pH inside a cell is generally 7.2-7.5, depending on the organism, but DNA is generally double-stranded under physiological conditions. Briefly explain, in your own words, why DNA denatures when placed in distilled water but not when it is inside a cell.

DRAW condensed structural (or line-angle) formulas for the four nucleotides of DNA (A, C, G, T), and identify each with their actual names (not just A, C, G, or T).arrow_forwardAccording to Chargaff's rule of nitrogenous base pairing, which of the following statements is correct? If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all thymine in a DNA molecule. If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all thymine in an RNA molecule. If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine equals the sum of all thymine in a DNA molecule. If all adenine bonds to uracil and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all uracil in an RNA molecule.arrow_forwardDNA structure depends on base pairing of its four nucleotides, A, C, T, and G. Nucleotide A pairs with T, and nucleotide C pairs with G. This forms a four-letter DNA “alphabet." Because DNA codes for amino acids in sets of three nucleotides, there are 4 cubed (4'), or 64, possible combinations, coding for 20 different amino acids. What is the best explanation for why there is no selective advantage for DNA to have five nucleotides (e.g., A, C, T, G, and E) with C pairing with either G or functionally equivalent E? It would be impossible to form the DNA molecule, because it must have an equal number of Cs and Gs. Because G and E have the same role, there would still be four functional letters of the alphabet. Replication would be inaccurate because sometimes C would bond with G and sometimes C would bond with E. There would be a five-letter alphabet with 125 combinations, which is too numerous. It is impossible because there are not five known nucleotides in the cell.arrow_forward
