In the 1950s, the race to solve the secondary structure of dna became intense. in an uncharacteristic rush to publish, linus pauling erroneously proposed a triple-stranded structure in february 1953. this model had the nitrogenous bases on the exterior and the sugar−phosphate backbones clustered in the middle. how does the orientation of the sugar−phosphate backbone in this model compare with the one proposed by watson and crick? do you think pauling's structure could exist in cells? why or why not?

4. rat liver is able to metabolize glucose by both the glycolytic and the pentose phosphate pathway. which of the following are properties of both the glycolytic and pentose phosphate pathway? a. nad+ is involved b. co2 is liberated c. phosphate esters are intermediates d. glyceraldehyde 3-phosphate is an intermediate e. fructose 6-phosphate is an intermediate4. rat liver is able to metabolize glucose by both the glycolytic and the pentose phosphate pathway. which of the following are properties of both the glycolytic and pentose phosphate pathway? a. nad+ is involved b. co2 is liberated c. phosphate esters are intermediates d. glyceraldehyde 3-phosphate is an intermediate e. fructose 6-phosphate is an intermediate
