DNA contains a code for synthesizing proteins. Three nucleotides in a row code for a particular amino acid. There are four nucleotides in DNA, which are abbreviated as A,T,C,G. The amino acids are joined to form a protein. Genetic mutations can occur in the DNA of individuals. Some mutations are harmful, some have no effect, and some might be beneficial to the organism. The table shows the nucleotide sequence of DNA that codes for a protein in one individual and the nucleotide sequence of the same segment of DNA in an individual with a mutation.

Question

Which statement describes the most likely impact of the mutation in the mutated sequence?

(1 point)
Responses

The mutated DNA will code for the same number of amino acids as the original sequence.
The mutated DNA will code for the same number of amino acids as the original sequence.

There will be no effect because the rest of the DNA is normal.
There will be no effect because the rest of the DNA is normal.

The extra nucleotide will be deleted before the protein is formed.
The extra nucleotide will be deleted before the protein is formed.

The protein formed will not be the same as that formed from the original DNA sequence.

Answer 1

The best response that describes the most likely impact of the mutation in the mutated sequence is:

The protein formed will not be the same as that formed from the original DNA sequence.

Mutations can change the nucleotide sequence, which may lead to a different amino acid being incorporated into the protein or cause a change in the reading frame, potentially altering the entire sequence of amino acids coded for after the mutation. This could result in a protein that is significantly different in structure and function compared to the original one.
