 [|DNA Mutations]

The Many Mutations in DNA  DNA mutations occur throughout a person’s lifetime. Damages can occur during this process, but DNA can repair them. As the person gets older, the DNA can’t repair as efficiently as it used to be able to. The risk is that parents can pass these damages on to their offspring; when this happens, every cell in the offspring’s body will have this error in their DNA. Some helpful tips to avoid these damages are to stay away from tanning too much, smoking, and UV radiation. There are many kinds of mutations. This includes frame-shift mutation, deletion, insertion, inversion, and DNA expression mutation. During frame-shift mutations, a letter is either added or removed from the sequence; this can make the DNA pointless. When mutations are missing DNA, it is called deletion. On the other hand, when mutations result in an extra piece of DNA, it is called an insertion. Inversion is when an entire sequence of DNA is reversed. The last mutation is when the protein is not changed itself, but how much is made of that protein is made. The outcome is many proteins can be made at the wrong time or in the wrong type of cell. This is called DNA expression mutation.
