Explanation:
What happens to DNA when a mutation occurs: An organism's DNA affects how it looks, how it acts and such. So if a change happens in an organism's DNA (which could be a mutation) can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
How does it affect translation: The DNA in our cells is translated by 'cell machinery' to create proteins. The DNA sequence of a stretch of a gene determines the amino acid which results in the proteins. If any change happens, it can result in changes in translation.
