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