Genetic Mutations Bad

Genetic mutations can be good and bad, depending on what kind of mutations happen. An example of a good genetic mutation would be a mutation that allows an organism to be more suited to its environment (like a giraffe’s long neck). Unfortunately, it is much more common for harmful mutations to occur, some of which can be small and involve only a single nucleotide, whereas others can affect a large region of a gene (Simon, 2017). Two potential causes of genetic mutations include spontaneous happenings due to error and mutagens, which are chemical or physical agents that affect DNA in a way that causes mutation (Simon, 2017).
While the spontaneous errors are not preventable, mutagens are. Many mutagens are carcinogens, which are cancer-causing
