Question

A mutation occurred in the third codon position of a gene, but the protein still functions normally. how is this possible?

Answer 1

the genetic code is redundant, so that mutations in the third position of the codon often result in the same amino acid being specified. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Answer 2

Answer:

The mutation is silent

Explanation:

Silent mutation are those changes that occur to the nucleotide sequence of a deoxyribo nucleic acid without any corresponding change to the phenotype of an offspring.

The change in the nucleotide sequence of a DNA that occur in a silent mutation does not affect the kind of amino acid/protein produced during translation. Hence, the protein still functions normally.
