No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
When a mutation does not change the result of a normal production of a protein is called harmless. This is because it does no harm to the individual.
the DNA sequence coding for the protein, leading to a mutation. This mutation can cause a change in the amino acid sequence, affecting the protein's structure and function. Defective protein synthesis can also result from errors in the transcription or translation processes.
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
dna in a cell needs protein and chromosomes.
Yes, a frameshift mutation will almost always result in a change in the final protein because it disrupts the reading frame of the genetic code, leading to a shift in the sequence of amino acids that are incorporated into the protein. This can have significant effects on the structure and function of the protein.

a silent mutation.
It is possible for a point mutation to not change the sequence of amino acids in a protein. This will result in the protein being unchanged and will not affect the phenotype.
Most genetic disorders result from a mutation that changes the amino acid sequence in a protein. This change can lead to altered protein function, which can affect normal cellular processes and result in disease.

A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
In a point mutation, a change in a single nucleotide can lead to a specific mutation. For example, a substitution mutation occurs when one nucleotide is swapped for another, such as A to T or C to G. This change can result in different amino acids being coded for in the protein sequence.
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
