Question

Genetic mutations occur in

• A. DNA
• B. RNA
• C. Protein
• D. RNA and protein both

Answer 1

The correct option is A DNA

Mutations are the changes in chemical structure of genes which are manifested in altered protein structure and function. Genes are the DNA segments that code for a specific protein product. Thus mutation in genes means mutation in DNA. RNA is synthesized using DNA template of gene which in turn serves as template for protein synthesis; RNA and protein are not part of gene but mutation in gene/DNA is passed to RNA and then to protein via transcription and translation respectively. This makes options B, C and D incorrect.

So, the correct answer is 'DNA'.
