Question

A mutation results in change in

• A. Sequence of amino acids in a protein
• B. tRNA sequence of nucleotides
• C. rRNA of ribosomes
• D. None of the above

Answer 1

The correct option is A Sequence of amino acids in a protein

The mutation causes changes in the DNA sequence i.e change in the sequence of nucleotide bases. Triplet nucleotide bases (codon) codes for one amino acid. Since mutation causes a change in sequence in nucleotide bases, this will directly have an impact on codon composition and therefore this changed codon will code for a different amino acid. Changes in the amino acid sequence may or may not produce a functional protein.

So, the correct answer is 'Sequence of amino acids in a protein'
