They built a scale model of DNA:
Correct answer: A. James D. Watson and Francis Crick
- A. James D. Watson and Francis Crick
- B. Maurice Wilkins and Rosalind Franklin
- C. P.A Leneve and T.H Morgan
- D. None of these
Explanation
The correct answer is James D. Watson and Francis Crick, who built the first accurate scale model of DNA with significant contributions from X-ray diffraction data provided by Maurice Wilkins and Rosalind Franklin. Their double helix model was pivotal in understanding DNA's molecular structure. Options B and C, while involving notable scientists, did not include the individuals responsible for the scale model of DNA. Option D is incorrect as there is a correct answer provided in option A.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
