The correct structure of D N A was first worked out by James Watson and Francis Crick in 1953. Their double-helix model of DNA structure was based on two major investigations, i.e Chargaff's rules of base pairing and study of X-ray diffraction patterns of DNA produced by Maurice Wilkins and Rosalind Franklin which helped Watson and Crick to design the 3-dimensional structure of DNA.

In 1953, the structure of DNA was successfully determined by James Watson and Francis Crick. They proposed the double helix structure of DNA, which revolutionized our understanding of genetics and inheritance. This discovery was made possible by the X-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin.
Structure of DNA:
- DNA, or deoxyribonucleic acid, is a long polymer composed of nucleotides.
- It is composed of three main components: a phosphate group, a deoxyribose sugar, and a nitrogenous base.
- The nitrogenous bases include adenine (A), thymine (T), cytosine (C), and guanine (G).
- In DNA, the nucleotides are connected together through covalent bonds between the phosphate group of one nucleotide and the sugar of the adjacent nucleotide, forming a backbone.
- The nitrogenous bases are attached to the sugar component and extend into the center of the DNA helix.
Prokaryotes vs Eukaryotes:
- In prokaryotes, which include bacteria and archaea, the DNA is circular and present in the cytoplasm.
- In contrast, eukaryotes, including plants, animals, and fungi, have linear DNA that is mainly confined to the nucleus.
- The linear DNA in eukaryotes is organized into multiple chromosomes.
Forms of DNA:
- Different forms of DNA have been identified based on their structural characteristics.
- B-DNA is the most common form, characterized by a right-handed helix and a uniform diameter.
- Z-DNA is a left-handed helix with a zigzag pattern and is less common.
- A-DNA is a right-handed helix with a shorter and wider structure compared to B-DNA.
- C-DNA and D-DNA are less well-known forms of DNA.
Correct Answer and Explanation:
- The correct answer to the question is option (a) James Watson and Francis Crick.
- James Watson and Francis Crick proposed the double helix structure of DNA based on the X-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin.
- Their work was published in the journal Nature in 1953, and it provided a breakthrough in our understanding of DNA's structure and function.
