Genetic Mutations: A Change In DNA

A mutation is a change in DNA. To be more specific, it's a change in the arrangement of bases in an individual gene or the structure of the chromosome which changes the arrangement. There are many types of mutations such as point mutation, frameshift, and chromosomal mutations. Each kind can either be very effective or not change much at all. It depends on the exact case and which kind it is. Some are more severe then others, for example point mutation is much less harmful then chromosomal mutation. Mutations can do nothing, cause conditions like down syndrome, or sometimes even death. People who have mutations are called mutants.bo Mutations can sometimes be very beneficial. One way they can help us is by allowing new versions of DNA combinations to occur. When these new combinations are beneficial they can create improved varieties of the organisms, resulting in more diversity and also gaining greater adaptability in the species.
Over time our bodies have adapted to tolerate lactose better. Before our bodies couldn't drink milk like we do now due to their genetics. Now our bodies have better adapted due to genetic mutation. Lastly a way that mutations can be helpful to the human body is the production of new and superior proteins. These proteins made wouldn't be able to be created any other way. By producing these new proteins we are advancing in evolution and gaining better survival characteristics. Mutations are not always harmful and scary as they're put out to be. Sometimes these changes in our DNA can help us. Depending on the case, mutations can also hurt us. For example a way that mutations can be very harmful is a protein called p53 which is necessary to prevent a cell from growing uncontrollable which is cancer. When a body has a mutation in p53 it can result in a cell with damaged DNA to reproduce. This is a way to get cancer. A mutation can cause a person to have
