Nope!
Sometimes mutations are "silent mutations", this means that changing out the base does not change the amino acid made (as many amino acids are coded by about 3 different base combinations)
Also, the mutation may only swap out an amino acid with a similar one, causing no change in the function of the protein it codes for.
A lot of times, several AA's can be altered (even w/ very different AA's), and the protein structure/function can remain the same.
Also.... DNA mutations that result in phenotypic mutations are sometimes a good thing: hence evolution... many small mutations causing an advantage over time.
:)
So mostly mutations that cause a base to swap out for another one are safe.
Those that delete or insert a base change the reading frame and that's bad!

Changes in DNA are called mutations?
That's correct. Mutations are changes in the DNA sequence that can result from errors during DNA replication, exposure to mutagens, or other environmental factors. Mutations can have various effects, ranging from no impact to influencing an organism's traits or health.
Mutations are changes in?

What are 4 things that contribute to mutation?
DNA replication errors during cell division can introduce mutations. Exposure to mutagens such as radiation, chemicals, and viruses can cause DNA damage and mutations. Environmental factors like UV light can induce mutations in DNA. Inherited genetic mutations passed down from parents can contribute to mutations in offspring.
What are known as gene mutations and occur at a single point in the DNA sequence?
Gene mutations that occur at a single point in the DNA sequence are called point mutations. These mutations can involve substitutions of one nucleotide for another (missense mutation), insertion of an extra nucleotide (insertion mutation), or deletion of a nucleotide (deletion mutation). Point mutations can have various effects on the resulting protein, ranging from no impact to severe functional changes.
What cell cause mutations?
DNA polymerase
Are all mutation detrimental?
Certainly not, some mutations create novelty in the organisms.
A characteristic of mutations is that they usually?
Mutations are random. They may be beneficial, detrimental, or have no effect at all.
What can cause changes in DNA sequences?
mutations
What makes mutations happen?
A mutation in humans is caused by a misconnection of DNA chromosomes and cells. Not all mutations are genetics some are just a fluke with the DNA match up.
Can mutations cause changes in DNA sequences?

How does polymerase prevent mutations?
It checks DNA for errors during replication.
What is a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.
Why are the two new DNA molecules the same as the original DNA?
Replication is an exact process without it we would all have incredible mutations.
What is a random change in DNA called?
Mutations are random changes in the sequence of bases in DNA. The word mutation may make you think of Ninja Turtles, but that's a misrepresentation of how most mutations work. First of all, everyone has mutations. In fact, most people have dozens or even hundreds of mutations in their DNA. Secondly, from an evolutionary perspective, mutations are essential. They are needed for evolution to occur because they are the ultimate source of all new genetic variation in any species.
