The type of mutation that stops the translation of a protein is a nonsense mutation. This occurs when a base substitution (point mutation) results in a STOP codon and thus stops translation of the sequence into a protein.
Premature Stop
NONSENSE!
A nonsens mutation can create a premature stop to the translation of mRNA.
a deletion of 2 nucleotides
Mutation
It is called Translation. The mRNA gets decoded into a polypeptide chain.
transformation
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.
Mutations not only change the DNA, but a change to the DNA will change the mRNA. This explains why a mutation in one generation can be passed on to the next generation.

Translation of mRNA into a protein occurs in the ribosomes.

The production of proteins is called protein synthesis. This is further divided into transcription, which creates mRNA from template DNA, and translation, which uses the code of mRNA to make polypeptides.
No, transcription involves the formation of mRNA.
Transcription
The termination codon on the mRNA strand stops translation by signaling the ribosome to release the polypeptide chain. This termination codon does not code for any amino acid and instead signals the end of protein synthesis.
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
