Document Summary
Practice questions for bioch 200 nucleic acids: atp and other nucleoside triphosphates are described as a high energy molecules. The term is used because the phosphoanhydride bonds in the triphosphate portion of the molecules are easily broken and the energy they contain is therefore readily available. By assigning the correct letters, match each statement with all of the structures to which it applies. _____________a, b, c, d, f__________: contains deoxyribose. Is or contains a nucleotide but not a deoxynucleotide. ______b, c, f____: contains a phosphodiester bond. Is or contains any one of the bases c, u, or t. Choice e may continue from the 5" phosphate, so may be longer than a dinucleotide (the final oxygen is not shown). However, as drawn, it may be considered a dinucleotide: contains a phosphoanhydride bond. ______________b,c,f_______________: contains a base found in neither rna nor dna. F: if a region of one strand of a standard (b-form) dna double helix has the sequence.
