 * Genetic Mutations

The effects of genetic mutations can be both deversifying and harmful to the human body. The negative effects of mutations can be the cause of a disease, or actually bring about diseases. On the other hand, mutations can simply be the difference in eye color. The most common cause of mutations is a simple mistake in the copying of DNA. Others include radiation, tobacco, and too much sunlight.

There are five different kinds of mutations, they are: point mutaitons, frame-shift, deletions, insertions, and inversions. Point mutations are the least damaging; it only changes one base of the gene sequence. Frame-shift mutations change one or more bases in the sequence, making them more dangerous. In a deletion, some bases are deleted, rather in insertions bases are added to the sequence. Inversions reverse the whole section of DNA. A key point to remember is to stay away from the things that cause genetic mutations.
