The experiments on DNA molecules in chromosomes for knowing the basis of inherited diseases are conducted by ?
Correct answer: A. Molecular biologists
- A. Molecular biologists
- B. Microbiologists
- C. Freshwater biologists
- D. Social biologist
Explanation
Molecular biologists study DNA, genes, chromosomes, and mutations at the molecular level to determine how inherited diseases arise. Students may choose microbiologists because they study microorganisms, but that field is not specifically defined by analysing the molecular basis of inheritance.

About Structure of DNA
DNA structure includes nucleotides made of deoxyribose, phosphate and nitrogenous bases, arranged in two antiparallel polynucleotide strands. Questions cover the double helix, phosphodiester and hydrogen bonds, complementary base pairing between adenine and thymine and between guanine and cytosine, and the significance of major and minor grooves.
