Rosalind Franklin used x-ray diffraction to record how x-rays scatter when bounced off the surface of DNA molecules.
Which of the following conclusions about the structure of DNA did her images support?

a) The DNA molecule was hydrophilic and extends upon exposure to water
b) The DNA helix was likely made of two strands
c) The DNA molecule was likely helical
d) The DNA molecule was uniform in width
e) All of the answers are correct

Answer :

Answer:

e) All of the answers are correct

Explanation:

The first X-ray picture of DNA taken in 1952 by Rosalind Franklin using the  X-ray crystallography technique revealed the helical shape of DNA. Based on this discovery, it was discovered later on that the DNA molecule was made of two chains of nucleotides and at high humidity i.e when exposed to water it becomes long and thin.

e) All of the answers are correct

The following information should be considered;

  • The first X-ray picture of DNA should be taken in year 1952 by Rosalind Franklin by applying the  X-ray crystallography technique
  • Based on this, it was seen later  that the DNA molecule was comprise of two  of nucleotides and at high humidity
