Solution

DNA double helix:

  1. Francis and Crick gave a double-strand helix structure for DNA in 1953.
  2. They discovered double strands of DNA with the help of X-Ray Crystallography invented by Rosalind Frankin.
  3. They received a Nobel Prize in Physiology or Medicine in 1962.
  4. They described double strands as two twisted ladders and gave their three-dimensional structure.
  5. Two complementary helical structure wrap around each other and forms a right-handed double helix structure.
  6. The Bases are stacked inside the double helix.
  7. The two strands are held together by a hydrogen bond.
  8. They published their DNA model in the journal 'Nature'.
