Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)

In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
