Renowned chemist linus pauling proposed a triple-helix structure for the dna molecule shortly before james watson and francis crick developed their double-helix model. in pauling's model, three polynucleotide strands lined up with their sugar-phosphate backbones oriented together in the middle of the helix. when watson and crick saw pauling's model, they knew that it could not be correct. they realized that pauling had not made use of a key piece of evidence about dna that had been discovered by earlier investigations. what key piece of evidence did watson and crick apply to their model that pauling did not apply to his? a. hershey and chase's identification of dna as the carrier of heritable information b. chargaff's finding that at and gc ratios are constant across phyla c. griffith's finding that a nonliving substance could transform living cells d. levene's identification of the chemical structure of nucleotides

Which description accurately represents how the use of biotechnology and watson and crick’s discovery change the field of medicine? (a) watson and crick discovered microorganisms. with today’s powerful microscopes, we are able to study microorganisms and how they cause illness or disease. because of watson and crick's discovery and modern technology, many lives have been saved. (b) watson and crick discovered x-rays. today, we use what they discovered and build x-ray machines, ct scanners, and pet scanners. these imaging devices transformed the diagnosis of disease. as a result, patients are receiving the treatment they need. (c) watson and crick are credited with discovering the structure of dna. through the use of technology, we are able to use this information to diagnose genetic disorders. (d) watson and crick discovered the microscope. with today’s understanding of complex engineering and ability to build medical devices, high-power microscopes scientists research and cure diseases.
