Likewise, the digital data sent from Voyager II contained one redundant bit out of every two bits of information. The Hubble space telescope transmits three redundant bits for every bit of information. How is entropy related to the transmission of information? What do you think is accomplished by having so many redundant bits of information in both DNA and the space probes?arrow_forwardWhich statement describes Linus Pauling's contribution to the understanding of DNA structure? a Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape. b Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone. c Linus Pauling conducted experiments to prove that DNA carried genetic information. d Linus Pauling studied DNA base pairing.arrow_forward
