Genetic mutations occur in:
Correct answer: C. DNA
- A. RNA
- B. Protein
- C. DNA
- D. All of the above
Explanation
DNA is the polymer of nucleotides that carry genetic information in the sequence of nucleotide bases. The functional segment of the DNA is known as a gene. The mutation is the sudden heritable change in the nucleotide and nucleoside segments of the DNA. Genes are the DNA segments that code for a specific protein product. Thus mutation in genes means a mutation in DNA. The correct answer is C.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
