Answer 2

Answer is option D - molecular structure of DNA.

Step-by-step explanation:

James Watson and Francis Crick discovered the molecular structure of DNA and mark a milestone in the history of the molecular biology and revolutionized biotechnology. They presented double helix, the twisted-ladder structure of DNA in 1953 and won Noble prize for their discovery in 1962. Though DNA was discovered in 1869. The X-ray crystallography data they presented showed that it is a helix structure composed of two strands coiled together.
